I would have said Sensible for SWOS & mega lo Mania but as an overall package Bitmaps get my vote!
I enjoyed most if not all their games, spending days/nights on Cadaver, Gods, Speedball II, Xenon II, Chaos Engine. Xenon was pap, and Speedball I never played.. CE2 was pap too!
Team17 were fab at what they did, but they were not overly original and I think Superfrog was/is massively over-rated. Project X and Alien Breed were both good, but Worms bored me after a while, and I have lost respect for the franchise cuz it's all they do now! Speris Legacy I just couldn't get into, AB3d and AB3D 2 were poo imo!
