Gungrave and Evil Zone come to mind.

Gungrave is kind of a poor attempt at making a 3D brawler with guns and its basically just you gunning down palette swaps of the same types of enemies over and over. The boss fights often range on ridiculously hard and its plot is pretty minimal (the anime is awesome though, especially if you like Mafia type stories). Still it had some clever things in and I just can't bring myself to actually hate it. Its just a fun "turn your brain off" game. It also used the whole "make the player kill the final boss in an emotionally charged cutscene" long before MGS3: Snake Eater was around.

Evil Zone... is a "fighting game" that basically pits together every single anime cliche and stereotype you can think of with the exception of a magical princess sailor girl. I don't really know if that was the designer's intentions either, I feel with the amount of details listed in the game they were actually trying to make something legitimate, which makes it even more funny. Combat is odd cause its based on projectiles and using psychic powers to trap people as the throws and well... it s really hard to explain this game. Its funny as hell, even if the dub is awful, and beating the game with characters unlocks massive amounts of background story and plot elements you didn't think this game needed. It' a pretty simple fighting game and most of the cast plays the same so it mostly comes down to who you like most.
