...or Lost: Via Domus as it appears to be called (poor latin and everything) elsewhere in the world.
Before my foray into the JRPG genre I played the Lost game (with Katherine watching closely as she's into Lost too!). I hate to say that like most licensed games, it's a simplistic rush job of a game with lots of minor annoyances. However, it does have a half decent plot to it and fits in with the mythology of the TV series fairly well.
Basically, I wouldn't bother if you're not into Lost, but if you are it's worth a look, though not essential by any means.
How come your trackback URLs have a different folder hierarchy to your blog?
Er, dunno.
