I have a garage and closet full of old games for those systems plus all the crap I bought on Steam and GOG sitting on harddrives, I could play for centuries. The only thing I don't do are mobile games because I can't see the darn things.
Oh yeah I have a couple of Mattel handhelds and Fidelity chess computers too, remember those?
I do remember those. :)
However, I started gaming on the NES when it first came out.
