Love Clover and Game Freak but, have to go with Bamco here.
Fond memories with some Tekken, Pac-Man and Soul Calibur games. Their work with Nintendo in Smash Bros, developed Star Fox Assault and some smaller assistance in titles like ARMS and Xenoblade 2. Also other games like Baten Kaitos which I am also very fond of.
Above all of that, my favorite RPG series, Tales of.
