I see Tomb Raider flopping on X1. Then flopping when it's released on the rest since you'll be able to watch the best parts on youtube. Microsoft effectively killed the reboot IMO.
I would say it's a definate grab for anyone who hasn't played it yet. For me it might just be a pass, because I've already played it on PS1 and then on Gamecube. I know the game by heart pretty much. I'll probably wait until it's $10 before I return to the mansion. A word of advice to the newbies though, be aware of windows! Woof!
