it's really simple actually in my opinion.
Nowadays it's all about the graphics, a game isn't a game if it doesn't look good is the going standard.
The times of a game being good because it had a lot of replay value and addictiveness are past us.
If you have to think too much to get a game done, it's considered "not fun" anymore and people quit to soon because of it.
But still.....there is hope
I have played numerous games over the last few years and found that some games are still worth playing, like:
Kingdoms of Amalur (huge game with good story)
Dragon Age 1 (2 was ok, but not as good as imo)
Skyrim
Diablo III (it's still fun for me
)
And a few others, as well as the golden oldies I play on my Voodoo rig, like UT99, Carmageddon 1+2, Final Fantasy 7, X-Wing vs Tie-fighter etc etc.
