The Lost Crown has not been released at all. It's now going for Q1 2008.
@Terrmax: for Sam & Max, they released a box set of all the episodes in 2007, so I believe other sites are counting that release as a 2007 game (even though some of the episodes were released in 2006).
And yeah, it gets a little funky when the game is out in Europe in 2007 but doesn't hit the N. American market (or the UK) until 2008. This poll is just for fun, so vote for what you've played I guess.
Edit: I took Lost Crown off the list (it didn't have any votes - it couldn't have, no one has played it
). I would also say the work involved with trying to figure out what games to put on a list for voting is a good reason why AG hasn't done this officially.
