I'm a bit of a retro gamer, but I've never had that big of a collection. Mine is curative--games that I KNOW I'll play.
I started out with a Sega Genesis (MegaDrive for those living in Japan, South Korea, and PAL/SECAM countries). Then I got a Nintendo 64 almost immediately after it launched. Follow that up with a PS1, PC (Windows 95, later 98), Game Boy Color (which I since sold), Dreamcast (which died after all of two days), and PS2. That sums up my formative years as far as gaming goes. I didn't get a Super Nintendo until 11 years ago, and I only have two games for it: Super Mario World and Secret of Mana. Most of my experience with the SNES library is through rentals, playing at my cousins' houses, or emulators. I always wanted a Saturn but didn't get one when it was new; I only scored one at a flea market over a year ago.
Only recently have I been a stickler for video quality with my consoles. Since I got HD Retrovision's Genesis component cable, I have not gone back to that shitty yellow composite cable that came with the system. Composite looked okay on a CRT, but plug it into a modern HDTV and it looks like SHIT! The fact that the Genesis had particularly bad composite video didn't help. RGB and YPbPr, on the other hand, are electric sex. Gaming with that is like eating at one of Gordon Ramsay's restaurants while composite is McDonald's. And you can forget about RF because that shit is CANCER! I tried using a SCART cable and SCART-to-HDMI upscaler (not a Framemeister) but neither of my TVs would accept the RGB signal. YPbPr is nearly identical visually, though the color space is different.
