Psygnosis was a bit of favourite of mine in the PlayStation-era: wipEout, Colony Wars, and Sentinel Returns were some excellent games. of course it all went a bit pear-shaped after the PS1, until the entire studio dissolved into the guts of what is now Sony Interactive Entertainment. Tactical Bacon Productions (what's in a name) has a great overview of Psygnosis, how they got started, and how they ended. Worth a view.
