Here's the dealio; I think the original X-COM is overrated. I think it has fantastic atmosphere, and I love the art style, but I think it gets too much praise just for being in the hard game club. There have been countless attempts to recapture X-COM through spiritual successors, and direct rip offs, and they've all been met by a fanbase that refuses to accept anything but the same exact game that was released in 1993. I imagine you can re-make the original X-COM, doing nothing more than updating the graphics and sound, and it would still be rejected for not being X-COM enough. 
 
2K Marin is re-making X-COM, in the first-person perspective. I think 2K Marin does some solid work, and I loved Bioshock 2, and I will most likely buy and enjoy the hell out of X-COM. But I think they're setting themselves up for failure in re-making a game that does not want to be re-made. I think someone like myself who is familiar with the X-COM series and loves a good first-person action game will be pleased, and newcomers who've never heard of X-COM may even be blown away, but those old school hard game club X-COM fans will piss and moan over every single change from the original and they will be the game's loudest critics.
