Funcom is making a LEGO MMO of its own and would-be players can now register for the game's closed beta. LEGO Minifigures Online is fully launching next year and before that point, there will also be an open beta. If you sign up for the closed test, you'll be eligible for the latter beta.
I'm a total sucker for collectables in games and trying to get all of the minifigures sounds appealing. There's supposed to be around 100 different ones in total -- at least to start. And Funcom mentions that certain physical minifigs will come with their virtual counterparts. The game itself looks to be about in line with what we've been experiencing in LEGO titles for years and years, which is what it is. Nothing revolutionary, but that's okay.
