Aaden: I think that whole PC-console-war is a misinterpretation of what happened in the last years. Consoles have always been there and both PC and console games were great. (One of) The real problem(s) is the explosion of development costs. Delivering even average graphics takes incredibly much work. But gamers demand more and more awesome eye-candy.
The portion of market and advancement is also fueled by other two factors, a) hardware and b) Users.
I believe PC games are expensive to make than console counterparts, because hardware in consoles remain the same and on PC the hardware gets updated every 9-12 months brining in new features.
So the devs spend considerable amount of time to bring in the new features to satisfy the users of the new hardware, to increase their coverage of sales. Couple these with users cribbing over new hardware features not used
(like a few threads back about DX11 and tessellation not present in Witcher 2 and someone was pretty badly screaming it foul that RED engine doesn't have it), the devs have less time to spend on other features_tweaks_polished modules.
When hardware advancement is held frozen for a few years, innovation kicks in..that is where games comeout greatly. Check the different magnitude of games in Consoles vs PC, I hate to admit but console have more variety and sometimes even better gameplay than PC only titles.
Also if in the new few years some GPU comes which is like 500 times faster, like 500 times more texture resolution, 500 times more fillrate etc etc...development cost for a single game is going to overtake the entire movie production cost of an entire year in Hollywood. Imagine the amount of work required to make a 500 times more polygon count model in a game!!!. + add textures + add shaders.
PC games are gonna be a sucker, and games are going to be pretty DUMB...unless and until the CPU's and GPU's advancement is held back..(which the manufacturer's won't, because they need to keep selling new stuff to keep sustainability)
Example: None of the new games have event a small portion of gameplay complexity of what the old games can do!. Check Ultima 7 against other games...lol...
End of the day, Console games in the future are going to be better and have more variety than PC ones (due to the fact that consoles hardware lasts for a minimum duration of 5+ years).
