Meh, I don't think it's a death blow, but, I'm starting to get bored with my XBOne. Not enough games. Still having a blast with TF though. My only real issue is that the console itself is so damn fickle.
I go to turn it on and take out a game (i.e. Fifa 14) and the disc tray won't respond or eject the game. Or, when it does eject the game, I put in a new disc and it doesn't read it. Instead it gives me a message about having to buy the digital copy. Only way to fix is a hard reset.
Other times, the game will be in the drive and it kicks me back to the home screen when I try and select it. Requiring another hard reset. There are also times where I shut the console down with a game in the drive. When I turn it back on, I go to select the game and instead of loading the game up, it takes me right to where I left off - as if there was no loading operation and as if the game was just left on all night. Only difference is that, when that happens, I can't log in to the game's server for online play.
SO...as much as I LOVE TF, and believe it is the best FPS I have ever played, I would rather go back to my PS3 and just wait until summer or fall to pick up a PS4. I'm that frustrated with the operational issues of my XBOne right now. It was running great up until last week and now it sucks.
