My younger cousin comes over today (like every few months) and we will be playing some couch coop games over the weekend.
So far we tried a lot of games and found some great ones along the way. Sidescrollers work sometimes, but third person and isometric is better. And I won't touch another twin stick shooter haha.
Do y'all have any suggestions, it's always so much work to find a good new game (as opposed to just going after steam review, buying, and returning within 30min of playtime because it sucked).
Honorable mentions:
Swords of Ditto (literally no one plays this, but it's a pretty neat co-op zelda-like
Darksiders Genesis (hack n slash)
It takes Two (co-op puzzle)
Children of Morta (great roguelite)
I also bought Secret of Mana, maybe we'll play this.
Phogs - simple puzzle platformer where you play an end of a 2 headed snake dog.
Lovers in a dangerous space time - share control of your spaceship to rescue cute animals. Take turns driving, manning the weapons or shields. Top down camera
Overcooked 1 and 2 - flammable chaotic cooking adventures. Top down camera.
Trine 1-4 are all pretty decent for some side scrolling puzzle action platforming.
Diablo 3 (on console as pc doesn't have local for some stupid reason) is a great action RPG.
I'll second Portal 2, and other's mentions of Lovers in a Dangerous Spacetime.
It Takes Two is fun, but if you're paying attention to the story I found it to be a bit preachy about what the writer thinks a good relationship should be.
Smash Bros and Mario Kart are both competitive not co-op.
I play smash with my 7 year old on the same team. We cooperate as teammates to defeat the other team. I'd call that co-op. The same can be done with Mario Kart, but whatever.
+1 for a tentative Overcooked suggestion but only if you think you and your cousin won't strangle each other in a high stress scenario. I can't play the game with my wife because she's too goofy and I'm too serious.
Bread and Fred looks like a lot of fun but I haven't actually played it yet.
Diablo 3 was fun playing couch co-op and reminded me more than a little bit of playing Gauntlet in the good old days.
Bread and Fred looks great but my wife and I turned it off after half hour. The mechanics are proper hardcore physics sim with very little room for error or hand holding. It honestly just wasn't fun for us.
I think there's a demo available so maybe try that before you spend money on it.
Honestly overcooked was stressful but manageable. The only time I wanted to strangle a friend (through my monitor) was in one of the "we were here" games because it was impossible to solve anything with him.
Edit: Oh I saw bread and fred on a stream a while ago (Jerma), forgot about that one. I think chained together was very much inspired by it.
It sure does. It's quite different to other games suggested in this thread, but if it's the kind of game OP is wanting to try then it's very good as a couch coop game (on PC, not sure if supported on other platforms). Though I get the feeling OP is looking for action or round based, rather than a quiet tending of a farm and exploring the local area.
A friend and I had a little fun with Ultimate Chicken Horse. It's a goofy little Mario Maker type of game where you create levels and challenge each other to complete them but I think you can also run through them cooperatively.
WRT Secret of Mana - maybe play the first little bit yourself until you unlock a second character, then save and you two can start from there. Trust me.
Also, I know it's a side scroller, but Castle Crashers is great fun if you haven't tried it yet.
Pretty much any of the SNES era arcade ports: TMNT, Knights of the Round, Sunset Riders... Though maybe not all of them in one sitting.
That's all I've got off the top of my head. Happy gaming!
9 Parchments - Surprising gem with some depth and a lot of replay value. Reminds me a lot of the Harry Potter universe. We fire this up almost every weekend. I recommend setting friendly fire to 'self' instead, as it encourages actual cooperative play.
Teenage Mutant Ninja Turtles, Shredder's Revenge - this is just a hack n slash quarter eater, but it's mindless fun.
If you like Enter The Gungeon, definitely try AK-xolotl. Same type of game, but more linear in a way. Rather than a single dungeon with multiple rooms to explore around, you go into a room, clear it, then choose 1 of 2 doors. Each door has a symbol to tell you which reward you will get after clearing it. Modding your weapons is much easier too.
Oh, it didn't have co-op when I saw it before, but it has now, wishlisted, thanks, but I'm playing through baldurs gate 3 and that is gonna take over 200h before I move on :p
I've been playing Broforce with my buddy recently. Lots of shooting and blowing shit up platformer but pretty funny if you're into the classic action movies like Rambo, Commando, etc.
Gears of War if you want to branch into 3rd person cover shooter. (Gears 5 is the only one on steam I think.)
The Lego games usually have couch co-op I think and I've enjoyed those a lot with younger people.
Super Mario Galaxy 1/2 - it sounds like your cousin is probably too old for this but this has one of the best "younger sibling" modes. They help collect and shoot bits. Which ultimately doesn't matter much
The Legend of Zelda 4 Swords Adventure - It's basically multi-player Link to the Past! Bonus points if you dig up a GameCube, link cables, and GBAs
Kirby Super Star - a mix of competitive and coop games
Super Mario World (any) - you take turns but if you don't go 6 levels without dying to his one it can be fun
Halo 1-3 + ODST - Great classic shooters, the campaigns are customizable for difficulty, and a little kid probably loves alien shooters
Borderlands 1/2 - Looter shooters with a sense of irreverance
Dead Rising 2/Off the Record and 3 - Zombie hoard murdering with combo weapons
The Simpsons '91, Battletoads, TMNT, Streets of Rage, etc - Beat Em Ups are great for multi-player
Rayman Legends is without a doubt my favourite coop platformer with fantastic music and great fluid controls. I strongly recommend it, it's tons of fun
And if you are into emulation most of ps2 era and before is designed for couch co op so hit the archives (top x lists on you tube makes it easy), depending on your cousins tastes
Lots of exploring and cooperating with irl co-players (E: you'd have to play on different devices, but one could play on a big screen, and the other can join and use their handheld mostly as a controller) and strangers, some puzzles/quests, some mild scary/dangerous parts, lots of lore, incredible graphics and good soundtrack. It's an open ended game (though some features only become available after your first complete run through) and there is an aspect of grinding if you want to get IGC for cosmetics but you're doing it flying through this gorgeous landscape, and there is a daily cap so you can be pretty chill about it, and IAP are pretty easy to avoid (for me anyway) and are never necessary for gameplay.
There are some issues with bugs, and the company growing and decisions clearly being made by shareholders rather then developers, but at this point it is still absolutely worth playing.
There were two isometric Tomb Raider games a couple of years back (Guardian of Light and Temple of Osiris which wasn't as good IMO). You could play in single player, but the co-op mode tweaked the puzzles slightly so you'd need to work together to complete them. And as luck would have it they're both on sale. The first is currently a whopping £1.27 on Steam.
If you fancy going even further back, there was a PS2 game called Kuri Kuri Mix by FromSoft. It may looks like it was made for toddlers, but it was surprisingly tough in places. You almost certainly can't buy that any more, but I'm sure and emulator and ROM site will do nicely.

I see lots of excellent responses, but one of my favorite games is never mentioned, so I'll mention it here, it's Out of Space it's essentially overcooked but calmer.
