As if a free, simple interface for enjoying these games weren't enough, Sarien adds a bizarre twist: (optional) multiplayer. When you go into a game, you'll be surrounded by identical avatars, all playing their own adventures. You can watch them explore and type commands (that's right, typing), or you can provide tips to your fellow players. It can be pretty disorienting to adventure game fans (and creators) but once you get used to the crowd, it's an interesting variation on these old games.
