I played Blitz: The League this past weekend, and it's AMAZING.
For those who don't remember NFL Blitz, it was a football game that was all about late hits, fast gameplay, and no rules.
Well, there have been many incarnations of it, but the new one strays from the original formula in a way.
First of all, there is no NFL License, because it would make the NFL look bad. So you don't find your favorite player or team on the game.
You start off with a team from the city of your choice, and with a nickname of your choice (Mine were the Honolulu Gangstaz), and you have to get them from Division 3 of the league up to the Division 1 championship. You do this any way you can. Make your players lift weights and use dietary supplements, or go the illegal way, and use steroids. Each game, you can wager money on your team, and try to win more money to afford equipment, services, and supplements to make your team better.
Also new to gameplay is "dirty hits." You can use dirty hits to have a higher chance of injuring an opponent or causing a fumble. When you cause an injury, the screen shows an x-ray of whatever part you're injuring. For example, if you cause a player's leg to break, it shows the bone, and then it snaps into pieces. If you cause them to tear a muscle, it shows the muscle rip. When your players are injured, you have a choice. You can either treat them, and let them sit out the normal amount of time, or you can "juice" them and they'll be back in a couple of plays. When I played, I caused a guy a spinal contusion, and his team juiced him. He was back in 2 plays, when he'd normally be out for 6 games. If you juice, and are caught by the league, however, then your team gets fined a large amount of money.
Of course, the story mode isn't the only part of the game, there is quick play, where you can play as any Divison 1 team, or your created team. It has all the same features minus the money gained after a game.
Overall, I would recommend this game to anyone (17+ since it's rated mature) looking for fun, whether you're a football fan or not.
