I had a few faves. I would say sensible software is my number one, mainly because they gave us Sensible World of Soccer & Cannon Fodder. Others would be Bitmap Brothers, Core, team 17, Psygnosis (thanks for killing them Sony), Microprose, Factor 5 (turrican II rules!!!), Lucasarts, Dino Dini, Gremlin, Delphine, Lucasarts and DMA design (now Rockstar North). Man, the Amiga was/is brilliant!!!!
