I've spent some time with the game, tried different variations and I think I can review this properly.
This game brought me back to the times when I was spending evenings on Newgrounds playing those old flash games, simulators included. There were a lot of them. And this is exatcly like them. Just better, more polished, funnier and more entertaining. Warning! If you think this is a FIGHTER game, don't buy it. It's 100% management/sim. Standard stuff : maintain your character needs while trying to get some cash while developing skills and winning fights. Sounds simple - but it isn't. The game encourages three developement styles - strength, agility or stamina based. But you must maintain some balance anyway to have any chance, for example buffing yourself to the maximum in STR will give you nothing because your fighter will be exhausted and on the floor after first 3 punches. I found the STR/STA based character the best, but it's my experience. Game offers some plot, some quests, a heck ton of pop-cultural references and gags and it's pretty in it's own retro style (if you dig it). There are moments when the difficulty just goes over the roof (like finishing the rookie leauge and then going to play offs), but with a little grind later they're managable. The whole fighting thing also requires some strategy and thinking - you can unlock many skill that will help you battle different types of enemies, depending on what stats they base on. It's simple but enganging enough. It takes some time to raise your fighter well enough to kick ass, but it's worth it. Fun little game.
