OK, looking at the new trailer it looks like they tried crossing the 50's stylization of Fall Out, with an attempt at TF2's art style, Then take Call of Duty, or as Spoony said it's more like Mass effect now. You put this all together, and you still don't get X-COM. Now I can see how they are trying to sell this as a Prequel to the old games, before they had all the high tech gadgets, but still, this is not an X-COM game.
Oh, and RTS isn't selling that, tell that to Sho-gun2, tell that to StarCraft 2. But you want to know what I'm afraid is abotu to happen, another Duke Nuke'em Forever. The studio already delayed the release once to rebuild the game, and I'm afraid they are goign to keep doign that because we keep telling them IT SUCKS!!!
