Good Ol Times

You can't fight nostalgia.

I guess the issue with the Steam / Origin / physical copy thing is you have lots of options, and you can choose to be picky because they all want your attention.

But if you are going for old games, your options are limited... so when you find a service like GoG you get happy with whatever terms they offer, because it's not easy to find old games nowdays, and reliving a part of your childhood is priceless.
