The game itself is great, very well judged for a mobile device. No defence (great decision), you just take turns on offence. You can actually RUN the ball this year and the graphics are a major upgrade.
The game is freemium so you know what that means - either make do with a set number of goes per hour and using a limited playbook or pony up for more. You can also buy new players to upgrade your team. For me none of this is a big issue; compare it to CSR - I enjoyed that, didn't pay a penny.
The negatives: I'll give them the benefit of the doubt as it's only been out a day but it's buggy as hell, drops connection and relies on your opponent getting back to you - so far I haven't completed a game against a human opponent.
That last point is going to make or break it for me.
