As a classic system collector, I've had interest in the Turbografx for quite a long time. It's just now that I've had the chance to pick up a new one for quite cheap. As for the gouging, I'm not going to buy any game that comes with the box without looking at the price. If I don't consider it has a fair price, I'll get it later. In fact, I don't see myself buying a game that costs more than 30$, and only if it's one of the pricier ones. I'll never pay 120$ for Air Zonk, for example, as some people has done.
Well Damon, it sounds like you're sane (and welcome to the forum, BTW, and thanks for starting a good thread!). I can understand getting into the system because you found a cheap deck and slowly adding games to your collection when the price is right. Starting from scratch in 2011 and deciding to go for all complete copies still seems a bit like self torture or a waste of money, but I guess it depends on what kind of "collector" you are. Do you have complete sets for three other consoles already on the shelf and the Turbo is just the next one on the list? Or are you mainly out to get some games you've always been interested in, picking up other titles if you find them cheap? I can relate to the latter.
I tracked down the U.S. games because I've always been more obsessed with the Turbo than any other system, the library is small, the ratio of good:bad games is decent, and I already had half of the rarities before the prices went nuts. On the flip side, I recently picked up a 3DO. I've always had an interest in it since borrowing one from a friend in '94, but, with none of the other factors in my favor, I've just said "f*ck it, why waste money?" and I settle for any scratched, loose disc with downloaded PDF manual that will let me play the games on real hardware without ruining my lens with ISO CD-R's.
When it comes to other systems, I like manuals with my RPG's and go for complete copies of stuff I'm really into, like Ultima and SSI games.
Anyway, that's what's reasonable in my mind. I know it's very judgmental and hypocritical to say that my U.S. TG collection is justified and those who came after some arbitrary cut-off date are crazy. Collectors are (mostly) all shades of grey and as long as you're not blowing money out your butt then you're cool in my book. What matters is that we all dig NEC consoles!
