It's prime football season, and it seems Gameloft's looking to take advantage of that with the release of NFL Pro 2013, one of only three fully NFL-licensed complete football experience games on the Play Store.
Presumably looking to take on the likes of EA's Madden franchise, NFL Pro 2013 claims to be the only free-to-play football simulation (kind of a niche, am I right?) currently available. Compared to last year's version, you're getting better graphics, a brand-new team management system, and a rather interesting first-person play mode (not sure how that's going to work out).
Considering we're using both free-to-play and Gameloft in the same sentence here, expect to start forking over cash to advance at some point or another.
