Nes (world cup soccer, vice project doom, Zelda)
Snes (smw, tons of others. Sales were plentiful and used games were great)
Ps1 (game shark! Ff8 is still one of my favorite RPGs. More the exploitable junction system, gf grinding and card game aspect)
Pentium 120 mhz (monster 3d 2, voodoo was the shat)
N64 (conker's bad fur day omg)
Dreamcast (piracy. Yus.)
And that sums up my retro stuff. Everything else is more.. "adult gaming", imo. Skill. Patience. Understanding the years of practice on earlier systems, etc)
