Ok technically I have way more SEGA games on Xbox (all of Yakuza, PPT2, Banana Mania, SEGA Genesis Classics, Sonic Adventure, Frontiers, Shadow Generations, Unleashed, etc.)
Not to mention all the SEGA games I emulate (Super Monkey Ball, Skies of Arcadia, Puyo Pop Fever, Crazy Taxi)
Also I hate Alien Isolation with a burning passion so consider it a stain on my SEGA fanboy collection.
