I have to admit, it still makes me excited when I see modders pushing the limits of StarCraft II's Galaxy Editor, an editor which is basically designed to make new maps or mini-games. Modder Greythepirate took it to the next level and pushed live 'Rogue Star', a tactical turn-based RPG.
It looks pretty smooth. Something to reinstall StarCraft II for, if you're into single player stuff and not interested in the game's competitive part.
