Yeah, the next gen debate
For my post I would define a next gen engine as one that can manipulate the high rez graphics that can only be played fully on the latest PCs or consoles. I think that was what he was asking about.
My understanding is that is where the indie game engines hit the wall. Personally I think next gen is overrated (game design is more important) but I think the graphical capabilities of the big engines is where you start paying the large dollars.
And of course I am only repeating what I have read since I am only cabable of making games to amuse my family and friends
