Minigore isn't a third person shooter; but here are some similarly cartoonish dual stick shooters: Meow Meow Happy Fight Bug Heroes Monster Shooter Max Adventure
I think Minigore counts as third-person, just not cartoonish enough (even if it kinda is). I guess we need to establish how a game is considered to be "cartoons." Does it need to have a tv show or something like that? Can pixel-retro type be considered cartoonish? Ones on top of my head: Crazy Bill Gunslugs INC Zombies. (cartoon humour i guess ) Apocalypse Max Gunman Clive
