Much like our Arcade platform, it's taken MobyGames a long time to add Mainframe games as a platform because, well, it's not one particular hardware configuration - rather a set of unique games on unique early computer hardware.
But the platform is here now, thanks to help from Kabushi & others, and already has 50+ well-researched entries going back as far as 1951 (!) - almost all added by excellent MobyGames contributor Vedder. Thanks again to all involved.
The best example is probably Stephen's Sausage Roll, which we've now added a basic description for. But if there are others that don't describe the basic gameplay in an understandable way, please add them to this thread and we'll make descriptions for them. Thanks again.
Secondly, MAT who is in 6th place overall, just bested 150,000 points for the first time, another spectacular result - lots of Japanese covers and screens in here. Congrats to both - and if you have spotted other milestones, please put them in the comments on this post :)
