oh jeez... where do I even start?
I guess a good example of how much retro gaming I do is talking about the computers I have put together to do retro gaming on, and you can guess from there how much I do...
all of these use mostly or entirely era parts and were built by me out of the exact parts I wanted:
386DX40 SCSI system (build log in sig!)
486DX2/66 VLB system
pentium 75MHz system (in progress)
pentium 166 non mmx system (in progress) (have all parts, incl voodoo1)
pentium 233 mmx system (in progress) (have all parts)
pentium II 450 dual voodoo2 system (changing from pata to scsi)
dual pentium III 1GHz system (mothballed for now) (need voodoo3 2000 agp)
dual pentium III tualatin 1.4GHz system (mothballed for now, even have v5 5500 agp)
athlon xp system (in progress)
athlon barton system (in progress)
athlon 64 x2 socket 939 system (mothballed for now)
core2 quad 3GHz system (finally found cpu, finishing build atm)
phenom II x6 system (current gaming box)
I don't even want to begin to try to list all the games I have (and play) on all of them... holy crap that would take forever...
