Tried both of these, while fun they aren’t quite what I’m looking for. Riftbreaker is definitely on a higher level then DINAO.
I would say go for it, AFAIK the game is mostly complete (IIRC only big things left are the last 3rd of the campaign and faction-specific models for buildings, possibly multiplayer) and while the bugs can be pretty bad they aren’t very common, usually get fixed quickly, and tend to only occur after major updates. Nothing I would consider inappropriate for an EA game at it’s stage in development.
