JMich: I'm excited for it as well, may be one of the few games in the last years that I will pre-order (still trying to find the SE here, else I'll be getting it from Game it seems).
As for all of you who complain about the demo, let me once again point you
here.
First mission will be the same (almost always), but for the second mission, replace the current enemies with Sectoid Commanders, Heavy Floaters and Ethereals, crank the difficulty to Classic (from easy that it currently is), change your weapons to laser, and try to survive. The demo is more or less a benchmark, not a proper demo, but the game does seem good. If only we could sack the Second in Command, we may have been able to survive the first mission without casualties...
At first I thought the game was pretty easy, but hey, first mission, tutoral. The I changed the difficulty to classic and lost the first mission in 2 turns. I like it!
My only gripe is the change from time units to 2 actions in general, but I'm also a boardgame fan and I've seen this done in some boardgames too and it worked. Didn't make the game any less strategic.
What I wonder though, since you don't really have much control over the layout of your base, will there be battles in your base?
