If you still have your PS2 handy Chaos Legion would be right up your alley. It's basically Devil May Cry (it is also made by capcom) but you can summon demons and fight with them along your side, freaking badass! Seriously there is nothing like having your main character just do his idle animation and have your minions tear the crap out of the enemy AI. I really wish they would have followed up with this game but, oh well, what are you gonna do? Tried to look for some cool game play videos for you for the summons that the main character had but all I ended up finding are a bunch of music videos of the damn cut scenes. Anyway it's definitely something you should check out.
