Games using LEGO?

Lately I’ve been getting into board games, card games, etc. And it got me thinking. LEGO would be a great medium for games.

I’m not talking about regular games that just happen to use LEGO as pieces… There’s Brikwars but I don’t think that’s really LEGO-specific enough. And there are various LEGO-produced games, such as chess and such, which are neat but not really innovative at all.

No, I’m thinking about a game where you have to build some structure out of LEGO while your opponent tries to stop you while building their own. I remember once I came across rules for such a game but don’t know what I did with it.

Does anyone know of any such games? If not, how about creating one?[tags]lego,games,boardgames,strategy[/tags]
