I'm looking at them and this is what it looks like to me:
Fallout 3 - Both look relativley similar. The only difference is, the shadowing.
SCIV - PS3 character and scenery detail looks a bit better.
Dead Space - PS3 character detail is much better. 360 surrouding is much better.
Star Wars Unleashed - 360 looks better overall.
CoD: WaW - 360 distance is better. PS3 close up is better. It's odd, some PS3 shots look better than 360 and vice versa.
Madden - Both look pretty much the same - PS3 looks better overall, imo. Though 360 crowd looks better (woo-hoo? lol)
MC vs DC - 360 looks better overall.
- 2010 MUST Haves: WKC, Heavy Rain, GoWIII, Fable III, Mass Effect 2, Bayonetta, Darksiders, FFXIII, Alan Wake, No More Heroes 2, Fragile Dreams: FRotM, Trinity: SoZ, BFBC2.
- Older Need To Buys: Super Mario Bros. Wii, Mario Kart Wii, Deadspace, Demon's Souls, Uncharted 2.
There is definitely more to list that I want, but that's my main focus there.
