I purchased this product after some personal debate because I quite enjoy Fighting-style video games and hoped that this would make for an easily handled and light hearted game.
After several hours of reading I've decided that it was a purchase well made. The rules presented in Fight! seem to be quite adept at simulating a fighting game. The book and rules do exactly what they promise to do in the product description. What would be complex or vague in other wide systems is very direct in Fight!. And since non-combat skills are quite widely available to characters and broad in their definitions it is perfectly possible to play the game with substance beyond the combats which give it focus.
If you want to play a role playing game based on any fighting video game or if you want to play in a campaign where martial arts and combat can be highly personalized and fantastic, than I greatly recommend Fight! The Fighting Game.
