I see your point, but for me it is more important the “entertainment per €/$” factor, and there you can’t beat indie games.
I’ve bought the whole Halo collection… that’s a metric ton of megabytes right there, but I’ve only installed it once and never again. In contrast, I’ve bought Loop Hero (about 200 MB) and haven’t been able to put it down since. That’s a lot more value for money, in my opinion.
