This debate's been going on for a long time now. Gonna make a case for those consoles to be added to this (almost dead) sub anyway.
Just cause they weren't made in the 90s, doesn't mean they're not old.
Add them to the sub, doesn't hurt to be inclusive. IIRC /vr/ includes the Dreamcast but not PS2 and Gamecube. I think those two can be rightfully considered retro.
