This game is a conversion of the classic Blood Bowl tabletop game. It takes the rules that required hours upon hours of bickering in real life to being automatically resolved. This saves you quite a bit of frustration, even if the dice rolls will still make your perfect team die horribly at the game's whim. If you liked the board game, you will like this game.
However, if you haven't played the board game, it's an acquired taste. You'll need to be able to accept that your rolls will dictate your fate, that your best player, that you've built up with the best possible upgrades, can die at any time, and that even if you play with perfect strategy, some times you will fail anyway. It's a brutal system, but it can provide a lot of long-term satisfaction if you have the patience for it.
Note: (The game is way more fun to play with a group of friends in tournament mode)
