I'll put it this way. I currently live in WL, since I go to Purdue, and I just ditched three Saturn games and they're on ebay right now (Burning Rangers, Shining Wisdom, and Albert Odyssey). I'm actually try to get rid of Saturn games, mostly because my Saturn internal ram battery has died again, so I basically lost ALL my game saves AGAIN (no way I'm playing through all those games again). But, there's no way I will ditch my copies of NiGHTs, Virtua Fighter 2, Daytona USA, and Shining The Holy Ark though. You can take a look at my game collection, in my sig, to see what I have. My games are still back at my hometown of Fort Wayne, but whenever I go home, I would pick stuff up.
As for Saturn games, I know Game Xchange, and there's a store in the Levee (I think there are called J&R Music/Video or something), who sells a ton of used games (although most are crap, I found a mint copy of Intelligent Qube for $10 there over the summer). They have a ton of Saturn games behind the counter, but I couldn't tell what they were (probably mostly crappy sports games).
I'm a little angry at Game Xchange, because I almost got Shining Force III for $7 (I originally traded the game in at Funcoland for $40, kind of miss it, but I couldn't save the data of the game anyway), but they couldn't find the game, and made up some excuse as to why I couldn't get it (I bet they were holding it, and accidently put it out).
Speaking of Valkyrie Profile, my PS1 copy is on ebay (Since I bought it for PSP, no one I'm touching my PS1 copy again).
As for McVan's, they sure do suck. They use to be really good, when Rob was one of the managers. Until Rob was no longer one of the managers, and working at Blockbuster instead, the store went downhill, with their outrageous prices on trades, crap selection, etc. I use to get awesome SNES games, Saturn games, etc. from them before, but that's not the case anymore. I can buy games cheaper at EB then do even color trades at McVan's these days.
