I feel like after you've played about 2 hours of this game you've basically seen all there is. It gets repetitive and boring very quickly. While it is nice that the game is very easy to mod, and there are plenty of mods, it doesn't really help the boring gameplay loop. Additionally, while not necessarily a critique, since it is a co-op type game, you are essentially required to play with at least two friends to not only stand a chance of progressing as the game goes on but also to be a source of engagement as the game isn't going to be giving you any itself. While making your own fun definitely works as a concept for certain games, this just isn't one of them. The fundamental gameplay flaws just shine through too much.
