OK obviously I didn't make it as clear. PS3 version $60 vs 360 version $2.5, Verbatim DL-DVD =P
Here's what I think of each console, very subjective so no comments on these please.
PS3 ver-
Pros: Free online, has a trophy system (whatever the official name is, idk) linked to Home, HDD install shortens loadings
Cons: Trophy system kinda useless atm, DLC comes out late, some people experience freezing
(Don't think low native resolution is a con because extra effects make up more than enough)
360 ver-
Pros: Can be run on modded console, gets an exclusive DLC, achievements, Live is more user-friendly
Cons: Dithering issue, DLCs come out late
I think they're pretty even.
DLC is not a huge factor to me because it comes out too late; if you get 1000 GS just in time for Ninja Gaiden 2 release date, that means 1/4 month GTA4 lying out waiting for DLC to come out. So 1 DLC for PS3 or 2 DLCs for 360, no difference to me. Star Wars Force Unleashed > GTA4 DLC personally.
