There's going to be a new Xbox 360 320GB hard drive on sale this March for $129.99, and it's going to include three full games with it. The included titles are Need for Speed: Hot Pursuit, Ms. Splosion Man, and Pinball FX2 with the Sorcerer's Lair table.
Ms. Splosion Man and Pinball FX2 are games that any Xbox 360 user should have in their collection. Need for Speed: Hot Pursuit is also an awesome inclusion thanks largely to it being a Criterion made game. Sure, it's a bit old, but still a ton of fun.
