I have played over 2000 hours of this game -- modded and unmodded. I just cannot get enough, and it never grows stale. That said, the AI is a bit weak, and head shots occur far too often. The AI issue is "balanced" by the game throwing tons of mechs at you. To counter head shots, get Cockpit Mods as soon as you can. I come to this from the original table top. So I like that it pays homage to that, while still keeping the game-play fresh. I tend to play the game 100% vanilla and un-modded. I find it more challenging that way. There is a very active mod community. So if the game isn't to your tastes as is, you an tweak it until it is.
