Orkhepaj: same , those just take up space and if something cant run with emus then i just dont play them , there are so many games out there missing some is fine
Do I recall right you mentioned somewhere being 14 years old or such?
Yeah, I must admit that back when I was 14, I also only cared about the newest and best looking games, generally wanting to fit in with my school buddies (playing the same games as them), or failing that, having something that they would envy. I couldn't care less what kind of video games my grandfather had played in his childhood, probably something shitty. Even worse, maybe video games didn't even exist back then!
However, as years went by and I had to get rid of my older systems that I liked a lot, or they simply stopped working, I started gradually feeling the sensation that many call nostalgia. I recall the regret when I sold my Amiga 500 with all of its games... even though I had kinda gotten fed up with the system and its games (which is why I sold it), I still felt bad thinking I will never see and hear some of the games I liked on it so much. I even went to record some of its games onto VHS tapes, that way archiving at least part of my personal gaming history to future.
So when many many years later I experienced emulators like MAME and WinUAE which could run e.g. Amiga games pretty much perfectly, I was quite excited. And still am.
So don't feel surprised if you at some point do get a similar nostalgic feeling. Not saying you will for sure, but it is quite possible, depending if there are games (and gaming systems) in your childhood which you enjoy a lot. For instance, I know two 20-something young adults who were overly excited when they were able to replay the N64 version of Mario64 and the Playstation versions of Spyro 1-3 and Croc: Legend of the Gobbos, which they played to death as kids.
Another reason to want to play older games is if you have simply amassed lots of older games that you haven't had time to play yet, but still want to play them. I have quite a lot of such retail CD games still around, like the 2005 King Kong game I mentioned some time ago. With them it is more like I feel I lose money if I am suddenly unable to install and play any of them.
It is a bit similar if you had bought lots and lots of DVD and Bluray movies. You'd probably want to keep some system around that can still play them so that your library of movies doesn't become dead just like that. (Then again, I've fixed that problem with my DVD movies by ripping them into digital video files which I can easily watch on any system, without a DVD player or DVD drive).
To me, wanting to (re)play some older games is no different from being able to see some old movies or listen to some old music. Do you feel it doesn't matter if "you" could never listen to Pink Floyd or Beatles classics anymore, or see the 1987 version of the movie Robocop or the movie Brazil, as there are always newer music and movies you can play instead?
