What the focus needs to be on the next few years (possibly decade) is to streamline the current game industry and gamemaking, instead of focusing on making everything bigger, BIGGER, BIGGER.
Like with Crysis back in 2007. No computer could handle it back then, but, due to people focusing on optimising such graphics-heavy games, combined with hardware improvements, means that today, Crysis can be run by pretty much any PC build for at least half-decent gaming.
The same needs to happen now. Instead of making games bigger and more grand (and thus, spiking the costs), we need to streamline the proces of making and game (and thus, bringing the costs down again).
But I’m not an expert, so who knows, I might be completely wrong.
