Please incorporate this absurd game-shuffling Sonic mod into every other video game
Every so often, the fine folk of Resetera take a break from their usual schedule of complaining that video games journalists get all their news from Resetera, and post a Thing Of Beauty. For example: it's thanks to Resetera member AstralSphere that I know about Alistair Aitcheson's Magic Box and BizHawk retro emulation tools, which - amongst other things - allow you to play old Sonic the Hedgehog games in giddy parallel, shuffling between them whenever you collect a ring.
