Just kind of curious because I haven't heard much talk of it since all these other major overhaul mods hit the scene. ACE hasn't really been updated in a while, but for those who don't know, it's an overhaul mod designed to improve balance and make the game more interesting without making massive wholesale changes.

Been using it for a little while and it is very good. Anyone else? Is there something that is perhaps similar to ACE?

Yup, i still use it too. Still works perfectly despite being old, and it's easy to use with plenty of other mods.
