I'm surprised no one has mentioned this yet, and if they did, I didn't see any threads about it.

Target advertised in their Sunday sales circular that a free ticket to ROTS is inlcuded on package if you buy Lego Star Wars for the Xbox or PS2.

I don't know if this is a Target exclusive, or if its all stores, but Target is the only ad I've seen the free ticket mentioned it.

I've already got my tickets to the midnight show, but if you want to play the game, it might be more incentive to pick it up and use the ticket for a later show down the road.

I bought mine at Game Stop the first week it came out and I didn't see any free ticket.

I saw the game at Target, and it's for a CHILD's movie ticket, and the ticket is inside the game.
There's a little blue circle on the front (the one that said that it covers Episode I through III on the original release) and for the free ticket one, it says it's good for a child's movie ticket up to $7.50.
