Frame rate and optimization issues currently leave CS2 anything but playable on Steam Deck, but it appears that Valve is working quickly to fix things.
It's a new engine, which is more than enough to warrant a new title imo. CS has been practically the same game many years and has been incredibly successful all that time. The community does not want major gameplay changes, just minor improvements. CS as a series is not like COD or Battlefield.
CS2 has much more advanced and consistent smokes, vastly improved graphics, more advanced netcode, competitive improvments alongside a new competitive mode similar to FaceIT, and loads of quality of life improvements. I think this is more than enough to be considered a sequel.
I’m pretty happy personally that the community server browser no longer looks like it was made in 1996. The new one actually works on my ultrawide monitor, so I can find servers on my own now. In CSGO, I had to have a friend find a server for us and then I’d just join him.
because source wasn't a sequel to them, just an engine port. Why counterstrike 2 is called 2, imo, just because Source 2
Being a new game in a series doesn't necessarily mean that its the next numbered game, especially to valve. Technically speaking, the other counterstrike project (Condition Zero, single player content) is also a thing.
As someone who played lots of cs1.6 let me tell you that cs source was extremely different from cs1.6. In no way was it just an engine port, you are talking out of your ass.
They should have called it CS: Source 2, then. The game hasn't changed enough to be considered a sequel. They made the same amount of improvements to this one as they always have in the last. Doesn't make sense to call it a full-blown sequel.
They probably figured that if Blizzard could get away with calling it Overwatch 2, despite being the same game, they probably could too.
