Super Smash Bros.: 3 Open Source Clones Compared
Super Tilt Bro and TUSSLE take different approaches to reproducing the Smash Bros formula. Super Tilt Bro is built to run on unmodified NES hardware via a purchasable cartridge with a built-in Wi-Fi chip for online multiplayer, and remains under active development. TUSSLE instead runs on PC via Python/pygame, is limited to local multiplayer, but includes a character-builder system letting players create custom fighters from sprites rather than using a fixed roster; TUSSLE's own development has since halted.
