It's interesting that even in about 2001, time of the Dreamcast and PS2, has work done by a team roughly 15 to 24 names in the credits. While Valve at the time likely had far more employees than Gearbox, it's still magnitudes of different scale when fast-forwarding to the closures, layoffs around Free Radical or Rainbow Studios. There is a video circulating on Youtube from the last days of when the former (+ Neversoft?) were closing their doors. Check it out if the time is able.
The game? Oh yeah it's okay.
