I'm that way too! I love buying old sealed games and opening them. I never had any turbo games when I was young, so opening new ones gives me an awesome feeling.
Totally. It also, in a way, makes me feel like a kid again -- even when its from something like the TG, which I didn't start getting into until around early highschool or so.
Another thing about it that I like is that it can be a great education into the condition of games that are fresh from the factory. I've bought more than one sealed game that had "factory" damage, usually just some minor manual creasing or something. Even if a game is brand new and has been untouched by human hands for more than a decade, sadly there is no guarantee that you will get a "mint condition" game. Thankfully, that is not my first priority.
