I'm fairly certain that most Playstation-brand gamers would have already witnessed many much more graphically advanced titles than Socom on PS2 now that we're 3 years into the lifecycle of the PS3 (if you're trying to imply the tired fanboy argument that Playstation gamers aren't used to impressive visuals).If my last shooter was Socom PS2 then I'm sure I would be blown away, but it's not.
Fyi, the last console that I owned was an Xbox 1, and I played the bejeezus out of all its high-caliber shooters and action games, including DOOM 3 and Splinter Cell. Of course, neither of those can even technically hold a candle to Killzone 2-- and are completely irrelevant to the discussion because they're so dated and inferior in comparison, technically--and Killzone 2 still strikes me as the technically most impressive game that I've seen in this entire console generation thus far.
