I've never played
Chaos Gate, but I've only heard good stuff about it, so I maybe I'll find the time to check it out now.
I played
Final Liberation multiplayer though, with Dioxine*, and have really fond memories of it. It was buggy as hell, at least for a turn-based game, and quite unfinished, but it was still pretty sweet (
Epic mechanics is pure fun). I can only imagine what some modders could do with it nowadays. (Look what amazing things they did with
Dawn of War, and it's just a filthy RTS.
)
* Empire is overpowered.
