Source?
Or is that just your opinion?
Do you need sources for a discussion?
C'mon...
It's not today's games that are bad, it's just the people's requirements that increased...
And you can't compare the games that were revived by the company... Like Duke Nukem...
It's hard to deliver something with the same quality as it was years ago...
It's easier to make a whole new game... You see the difference?
Before, people only could care about gameplay, storyline...
Nowadays, there is graphics, sound effects, music, gameplay, storyline, character development, immersion level, physics, realism, animations, bugs, etc. It's hard to make a perfect game... And it will get harder and harder.
