you forget PVP. Thats the reason I have been playing League of Legends for ten years, it is a 5v5 game lasting 20-40 minutes. Here the code is just the environment for the players, like a field, a goal, a ball. You have things like skill expressions and some people find totally weird ways to play the game and win. League of Legends is much closer to sports than chess.

Also, dont you dare hating on my bullet hell games!
