Gaming hasnt really made a real leap in content since the PS2 and original Xbox. 360 and PS3 expanded on the same concepts, but in so many years, i havent seen anything 'new' that adds to the formula. Just better graphics and framerates.
I think they redo much of the same for a new generation of players. How many people under 20 played KOTOR or Jedi Outcase, for example.
This is why i am bored with gaming. Same old stuff, nothing really 'new', no new experiences. I can think of so many examples.
