One of the internet's greatest resources for old games is coming back thanks to the work of some dedicated fans. The original website OP had moved on to actual life matters (how selfish!) and the site had been left untouched for years. Now it's back, with new people running it. Downloads aren't up yet, but when they are they have thousands of games going back to the Amiga and Atari ST, etc, as well as oodles of hidden PC gaming gems up to the present day.
This site was like a little slice of heaven back in the day. It's great to see it back, especially for any fans of old school gaming like me. :)
