Wow, that's actually pretty impressive that they managed to handle 3D like that on the 3DO. I'm pretty sure this was a late release, so it would have been interesting to see how the whole system would have fared if this came out a couple of years earlier.
High price tag probably one of the 3DO's worst failings, but from what i've seen of it, it was a very capable enough system, seems somewhere in middle ground between a SNES and Playstation 1. sort of half-way house (better at 3D than SNES, but not as good at 2D).
Things like Starfighter 3000, Space Hulk, Foes Of Ali, Return Fire, WC3, The Need For Speed etc looked very impressive for the time.
Pity it got such a poor port of Doom though, guess by then industry had written it off, so were'nt going to worry too much about coding a best possible version for the hardware.
