We’re cheapskating brothers: that sale got us, and we haven’t supported the game in all that time since!
Well, “early access” in this case doesn’t mean the game is half-done, really. It is more of an honest way of saying, it’s a computer game, it’ll be in development throughout its lifetime. The game is fully and enjoyably playable as it is. I ran through a couple of scenarios this morning, one from 'Nam and one from Normandy. While the UI is a bit odd, everything is fully functional. I’ve seen supposedly finished games with a lot less polish and working parts.
