Y'all know how Desert Island works? Pick the games that you would pick if you had to play those games for the rest of your life. Just to keep it simple, let's just imagine that if you want to pick an online game that the servers will always be online and there will always be people to play with. Let's limit ourselves to 10 games.
I will start, of course.
Unreal Tournament
Pavlov (Or Counterstike, same thing pretty much)
Beat Saber
Dwarf Fortress
The Binding of Isaac Afterbirth+
LittleBigPlanet
Super Smash Bros. (Iunno which one, Ultimate I guess. Or project M)
-Super Street Fighter III 3rd Strike
Elite Dangerous
Lovely Planet (I'm probably the only super fan for this game lol)
Yes, lots of games that have a high skill ceiling or near infinite potential. I would love to see you guys' lists.
