Mike United 007. As I had somewhat expected, the same idea for LEGO Gears of War, was giving by more than one person and it seemed reasonable to therefore pick the first answer regarding that game suggestion. Here is the answer;
i would have to go for one of the best selling titles Gears of War, and call it 'Lego Gears of War Trilogy'. and roll all the gears of war title into one, or do another title that has more then one disc.

I would predict this would sell million's of copies, for such a great game.
Would love to see the berserkers, locust's, Corpser, General RAAM etc. in Lego form. Let me rev-up my lego Chain saw on my lancer and cut'em up into millions of pieces

Plus i found this -
look how cute they are

I'll send the game tomorrow morning and should arrive by midweek. There'll be another chance to win a game next week.
Good luck for next time!
