Lego Universe is F2P nowadays
I just stumbled on this while following some links, seems Lego Universe has adopted an F2P payment model.
While I have not played the game yet, it seems from other posts I have seen about it that it has struggled a bit in the past, which is a shame. There should definitely be a market for some good building-games in the multiplayer space (looks at Minecraft). Maybe this transition helps.
Will probably end up trying it at some point now.
