I gotta be honest - at the time they came out, $100 was about the going rate for Chrono Trigger and NBA Hang Time. Phantasy Star IV was the same was on the Genesis, as was Virtua Racing. I specifically remember shopping in a Target store when Chrono Trigger was new, and seeing it retail for $89.99. After sales tax, you're pushing $100, easy!
Cartridge games used to cost *A TON* especially when larger-format games (32 megabits of memory or more) became the norm for the SNES. The night I bought my Nintendo 64, in April of 1997, I remember going to Bigg's (remember that store?) and buying Star Wars: Shadows of the Empire for $84.99. That's just what N64 games retailed for back then - ask anyone that got Super Mario 64 or Pilotwings on launch day.
OOOOOOK, enough of that rant!
Most I've ever paid for a game: $160 for Panzer Dragoon Saga. I no longer own it, but I'm pretty sure I made my money back when I sold it. It's an EXCELLENT game, for those of you that haven't tried it out. If it didn't sell for $200+ nowadays, I'd recommend that every Saturn owner pick it up. If the going rate were more like $20 or $30, it would be a no-brainer.
Most prized game in my collection: Phantasy Star Online Version I & II Plus. I bought it when it was released from Best Buy, and Paid $29.99 plus tax. The game was released as a "budget" game at the time, though there aren't that many of them out there. Honestly and truly, I *LOVE* that game, and still play it on a regular basis. I only have about 30 games in my collection, and that one isn't going anywhere!
Runner-up for most prized game: Phantasy Star II for the Sega Genesis, complete with case, manual, maps, and hint book. I'm a fan of the entire Phantasy Star series, although this one and PSO I & 2 are the only ones I still own. Personally, I think that Phantasy Star IV is the best game in the series, but PS II has a lot of nostalgia for me. Seriously, a lot. I wasted a lot of time in high school with that game, and when I think of it's mindbender of an ending, as well as it's infamous "death scene" for a certain party member, I get chills. The day I beat it was one of my favorite moments as a gamer, and even though the game is clunky, poorly translated, and confusing as hell, I'll probably keep it until my dying day. It just means a lot to me, you know?
Anyway, awesome thread! I can't wait to see what comes next!!
