Realm of the Mad God
Realm of the Mad God takes the compulsion loop of a conventional MMO and boils it down to its essential nutrient broth, eschewing all the frippery and getting down to what such games are all about: Kill, loot, level-up, kill some more.
With NES-level pixellated graphics, frenetic top-down shooter play with WASD movement, and permadeath, it feels like a game from another era, yet informed by the tropes and techniques we've come to expected in dikuMUD-likes; games from another era are not, obviously, browser-games and massively multiplayer. It's a game that might have been developed in 1985, if we had an Internet in 1985.
I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.
