My registration finally got approved, so today is my first day for posting here, although I've been lurking for a few months.
I live in the Chicago-land area, and my personal TurboGrafx history follows:
I had a friend back around '90 who had a TurboGrafx-16 and I would see his great games (Cadash, Alien Crush, etc...), and I always wanted to get a TurboGrafx, but I just didn't have the funds. I would even play Keith Courage or whatever sample game that any retail stores in my area had on display, and I would drool over all of the 'neat' TurboGrafx-16 games and such. (All that I had experience with at the time was Atari and NES.) Then around '95 or so after I had a job, I picked up a TurboGrafx-16 system and about 20 games (most has the jewel case and instruction manual). I don't remember all of the games that I had, but I think that I had 2 CIB copies of Tonma and a CIB copy of Magical Chase - just kidding. Actually I know that I had Order of the Griffen, Cadash, Galaga '90, Drop Off, Tricky Kick, Legendary Axe, Ghost Manor, Blazing Lasers, Victory Run, Sidearms, Double Dungeons, Final Lap Twin, Dungeon Explorer, Deep Blue, Neutopia, Neutopia II, and Keith Courage, but I can't remember the rest. I never could find a 5-player adapter or extra controllers, so everything stayed 1-player. Then, in '97, I boxed everything up for a while. Not long after the Gameboy Advance came out, I became enamored with it, but I just didn't have the cash at the time, so I made a stupid trade around 2000. I traded my entire TurboGrafx collection to someone for a new Game Boy Advance with a new copy of Advance Wars and one other game, the title escapes me right now.

Now, I'm mentally kicking myself over that trade. About a 15 months ago or so, I decided to get back into retro gaming, and I really missed my TurboGrafx, so I eBayed some stuff, found a few things at a used video game store, and just yesterday picked up about another 17 HuCard games at a local Chicago-area convention, so now my TurboGrafx collection stands as follows:

HC - Street Fighter II
I have no CD games, since I have no way to play them, but I may consider getting into those if I can find a good CD add-on or TurboDuo that I can get.
Anyway, now I'm trying to decide where I'm going with this TurboGrafx stuff. I have decided that whatever games I have, that I do want to at least have the Jewel Case (or maybe a decent repro case) and the original instruction manual, which means that I need to upgrade my HuCard-only games, but after that... Do I want to try to collect the entire U.S.-released HuCard set? Do I want to just get a couple more of the good games, while ignoring the expensive ones and the not-so-good-ones? Do I want to venture into the CD games? Do I want to venture into the PC Engine games?
