Yeah, I did see the footage, and it does look pretty decent so far. I fully admit that I would much rather have an XCOM reboot that sticks to the original formula but with modern improvements (graphics, interface, etc), but I'm also not one who is against new ideas. With that in mind, here's what I liked and disliked form that demo:
Pros: I like the pre-mission elements, as well as the ability to choose which mission to take on next. I also like the way that research seems to be handled in the game. The different agents appear to have enough differences between them to make different party choices change the gameplay and tactics available.
As far as gameplay goes, this game definitely looks like it was inspired by Mass Effect in terms of the tactical wheel, party orders, etc. I don't think this is a bad thing, as it also looks like it will potentially throw a more diverse range of challenges at the player compared to ME and actually take advantage of such features in a positive way (meaning more tactical depth than ME).
Cons: I really only have one major gripe given the limited time of the gameplay video: The level shown appears to be very heavily scripted and extremely linear. The cerebral aspects of the game might make up for that (in terms of it being an FPS), but I hate linear, scripted level design. This approach to level design is the biggest reason why I have lost interest in FPS games over the years; it's just too sterile and boring for my tastes, and the lack of more open levels lessens the tension that is present in other squad-based games, where you have no idea what to expect behind each corner as you slowly explore a level (Jagged Alliance 2 comes to mind). I guess it's too much to ask for non-linear levels from modern games…
So all in all, the game definitely looks far more promising than I ever thought it would. Even though it won't come close to living up to XCOM's depth and cerebral qualities, it still looks like it might be enjoyable. It will probably be worth playing, but I'll have to see more details and better, less scripted and linear levels to get too excited.
