>> And there are so many quality indie games you could get for the 25+ dollars you'd spend generating the code.

But those games have already been designed a specific way, based on the developer's ideas and imagination and vision.

If you're the sort of person who always thinks along the lines of "I wish there was a way to upgrade spells" or "it would be great if you could open this door and see what is behind it" or "I hate the way orcs and goblins are friends, they should actually fight each other"

That has always been the issue with games: they capture the imagination... and then stop there. There's no way to expand them the way you want (except for submitting requests/wishes to the devs and hope they listen and add it in a short enough time period) and customization options are always very limited.

AI, on the other hand, empowers everyone to bring their own ideas to life. Sure, those ideas may not be great, or the execution may not be great, but at the end of the day it's a way to express one's imagination that would otherwise take years to do.
