What's the Big Deal with GameStop's deals this week? It's the Simpsons Game which will be available by the end of the month. The price cut for the Sony PlayStation 3's 80 GB console is also spotlighted this week, plus a couple of discounted games for the Xbox 360, the PS3, and the PC.

This week's promo is a free Homerball when you reserve the Simpsons Game (PS2, PS3, Xbox 360, Wii, PSP, DS). The Homerball is a little toy doll of Homer. If you recall, getting as fat and round as a watermelon is one of Homer's powers in the game. Also this week is MotorStorm, bundled with the 80 GB console.

Discounts this week are WarTech: Senko No Ronde (US$ 9.99), Untold Legends: Dark Kingdom (US$ 19.99) and Vanguard: Saga of Heroes (US$ 49.99). The 20% trade-in credit for reserving Super Mario Galaxy is still in effect, and probably will be until the game is finally released next month on November 12.
