Things That Make Me Smile: 8BitMMO
Ah, that's the stuff. I knew I could trust IndieGames to provide a Friday afternoon-completing link, and so they did: 8BitMMO! Yes, it's a super lo-fi MMO that looks like someone made it on a Commodore 64, but is actually pretty contemporary with its open construction options, PvP, and all the jazz that makes the massively multiplayer world so appealing. It's also free in your browser right here. I've posted the trailer below if you want to have a look but can't be playing Java browser games at work or whatnot. Lovely, lovely.
