Today, my Dad is leaving US to go to the Philippines. Before my dad leaves, he gave me $15 bucks for us to buy us a first 360 game.

Yesterday, my brother bought a new 360 S at Best Buy along with his new laptop so he can give the other laptop to my sister and my mom at the Phlippines to talk at Skype. I was really happy that we got a new 360, and whats good is that we own the Wii and the PS3, so it looks like I'm gonna be a one happy gamer.

But the problem was that the console is 4GB, cost about $199, which is cheap, yet small size. I can't tell which game that could fill up the entire thing in one size. Other thing would be Xbox Live. I mostly play online on the PS3, and feeling that Live could be expensive for me, but I'm not really sure about it.

Already my Dad has left home, only just me and my sister at home,also grandpa and our dog, but we still have my big brother and sister, who is going with my dad to say goodbye, other at work. Looks like we might have to survive 2 weeks without my mom, dad and one sister.

Since I have $15 bucks from my dad, I have to choose wisely for myself, and my siblings. For my question, which 360 game is the best under $20 bucks at Gamestop or some other store?
