Top 5 graphics engines in 2009 IN YOUR OPINION

[inverted3reality]

I was going to argue but I realized this was a opinion thread :P
My 5..

5. Batman: Arkham Asylum
4. Forza 3
3. Killzone 2
2. Gran Turismo 5
1. Uncharted 2

Special nominations for inFAMOUS for doing an absolutely amazing engine in _some_ parts, but failing really bad with animations. The next revision of their engine is going to be amazing!
