Got this the day it came out. Installed very quickly and updated direct x as required. The requirements are very low - in todays standards, and therefore you don't need an expensive computer to run it perfectly.
I went with a normal sized database and chose both scotland and england - the game runs a lot faster than 2010, and it's a lot more realistic - the negotiations are a lot more fun as it feels like you're actually having a conversation. Additionally, the match system makes you think you're really watching your team - the graphics are the best I've seen for a management game. The editor is back too, and is very easy to use - it now has .xml files which you load into your default database to change it slightly. Again, can edit anything you want - from countries to staff.
All in all, it's worth the money and it is indeed an improvement from 2010.
