Are there any good games for under $20?

if so can you guys list them

forget that guy! call of duty 5 is great BUT call of duty 4 is better! i don't know why butit just is. Trust me when i got my ps3 i got cod 5 as my first ps3 game but then i bought cod4 because my friend told me so and it is awesome you cant even tell the difference between the graphics or that it was made two years ago.

I got $250 for my birthday. I really want Guitar Hero: World Tour but I only have 2 wii remotes and I don't know if it is really worth it. Is it? If so explain and be specific. If not explain why not and please suggest what i should buy.
