Meh... not exactly dos, but C-64, old console and many arcade games are in the same league. While it would definitely give me a smile to see some of them back in action, I don't think I could give them more than a few spins, past is past
Might have a lot to do with having already beaten them.
Im like that with games even from 5 years ago.
But hey, 100 dos games, a few spins each, hundreds of hours entertained
