No idea what happened, I just installed it off the disc anyway, didn't bother installing Steam again.
And same, I always play the same way in every game but getting them to play that way in this one is a bit trickier as I haven't really got used to the new tactics creator...but i'll get there. Think I might just play as Man City until the january update, I don't want to get too far with a Saints save then have to start over.
