There are many reasons to put his game down and run, bad replay value, terrible story, not funny, and a whole others....

User Rating: 2.5 | The Grim Adventures of Billy & Mandy PS2
If you want a decent game with a good story and cool fighting mechanics, well then you want others like Tekken and Street Fighter. This game is terrible and downright stupid, and can be racist at times, but that's not much of an issue (though I hate how they make fun of the black kid Erwin a lot.) The game's story is very stupid and doesn't cover much of why you payed $20 for this load of horse crap. Somebody (think of the biggest idiot on the show) has released Grim's Mojo and now everyone is fighting each other, and that's it. Apparently, they weren't affected but fight each other in down right ugly environment and traps (like falling spikes) aren't helpful. The AI is stupid and will just run for boxes so they can throw stuff at you, no wait, they never even come near you. Then you watch some cutscene after every round to add some non-hilarious slapstick then goes on to the next round until the last cutscene (SPOILER!) and find out Billy has done it to release, as much stupidity it has, I'll say it. He opened it to release Mo and Jo (SEE???!!!) Then there are missions where you have a team deathmatch, deathmatch, and capture the flag. Surprisingly, there's no online modes. Just bot matches and a co-op campaign. I really couldn't believe what they did to a really good show to it's game tie-in. Well, now you know...

Good- co-op campaign is fun, kinda funny

Bad- racist, bad AI, bad graphics, just plain idiotic, a bad name for a great show, not funny
