LEGO game, coming this summer for DS, is not built around any license. Well, other than the LEGO license. But there's no Batman or Star Wars or anything like that: this is pure LEGO.
LEGO Battles, developed by Hellbent Games, sounds like a kind of LEGO-based strategy game, in which players build and defend bases in the LEGO Castle, Pirates and Space Themes, using units mixed and matched from the sets. The press release promises "pirate swordsmen fighting side-by-side with wizards and aliens; dragons battling ninjas; and pirate ships launching broadsides against spacecraft and knights!" In addition to the single-player mode, local multiplayer battles will also be available.
And because we haven't said the word "LEGO" enough in this post: LEGO.
