Another thing I need to ask about, what do features have to do with power? The Wii U has a tablet controller so it must be a generation leap above the Xbox One and PS4. That is the argument you are making.
And let me be clear, the PS2 was significantly weaker than the Xbox and GameCube. They released around two years after the PS2 I think, but regardless there is a significant power difference.
But a broken clock is right twice a day.
It's all part of the same equation. Capability. You build the feature set that enables the games to do the things they do. You put hardware - hardware many times more powerful than what was in the PS2 - behind it. Combine the factors and you get games that could not exist on the PS2.
A....,eh. You know it already.
Halo pic was bad, sorry, but the PS2 one was not photoshopped (to my knowledge)
Here is some footage of TLG (which did to be fair, suck more power out of PS2 than any game had any right to).

SOTC ran like absolute ass - unplayably bad IMO ((15-20 FPS)) while being far less graphically impressive than either Halo 2 or Chaos theory.
