Really good video, seeing every release listed sequentially really shows how dependent on independent contractors Psygnosis was for the overwhelming majority of its successes.
The only complaint I have really is that the PS1 era is basically only half the story, in many respects the most important and formative influences/relationships were forged in the 16-bit home computer era with Ian Hetherington making hand-shake deals with what turned out to be a whole generation of UK talent. Bizarre Creations, DMA design, Reflections, Travellers Tales, all started here pre-Playstation.
The key thing is to remember that all these guys only got their hands on Playstation dev-kits so early thanks to Ian H.
In retrospect this was huge for UK dev because prior to that most of their output had been confined to the local and European markets. Finally they had a springboard into the global gaming scene, crucially one without all the logistical difficulty and manufacturing convolution of the 16-bit cartridge console scene.
