For one I would love to have an SGI workstation, I still have CG magazines from this era and its plastered everywhere in the ads, and I'm still amazed at the graphic output (so smooth) and what we had in the 90s.

I'd imagine something like this would've been used to make Crash Bandicoot and likes. It'd be really interesting to play games built on this thing.
