The problem is that those mechanics either evolved or died off - and it happened for a reason.
What's (if anything) is wrong with decade old mechanics? (Especially when the recent mechanics are often thought to be over simplified.)
I see no good reason to scorn modern game design or avoid wider audiences available today.
If anything it should be preferable to update the mechanics and keep the best parts of older games intact - then they can appeal to both groups.
Try the BIoware or Bethesda forums if that's how you look at the industry and it's progression.
Have a nice day.
