After the installation debacle yesterday, I was able to get on and play for a few hours. Logged out and went to bed. Woke up this morning and the game wouldn't launch. I went to the MS store to try to launch it from there and it told me that my game was corrupt and I had to reinstall.... WTF?!?! I was playing it just fine the night before...
Sega needs to dump MS as quick as possible.
