While consoles are becoming more PC like in a lot of ways, there's still quite a few key distinctions. I had a phase when I went heavily into PC gaming but now I'm starting to prefer console gaming again.
I have a fairly strong PC that I plan on keeping relatively up to date to play certain games but aside from that, don't plan on spending much else on it, budget or time wise.
The reasons are largely of convenience and ease of use and of course, some compulsions that I have when I game on PC. I think the first two are probably relatively self explanatory so I'll just focus on the last.
I realized that I spent far too much time tweaking to get the optimal experience rather then playing games. Sometimes it was tweaking optimally and others, to fix issues. Regardless of which it was, it took up a considerable amount of time. And I had this compulsion because when you buy certain parts (980ti), you expect a certain level of performance. And when I didn't get that, I didn't feel like playing the game until the issue was fixed.
In part, going back to consoles solved both these issues. You don't have to trouble shoot and fix issues as much as PC (nowhere near really). And the compulsion no longer exists because it's a machine I bought for 299-399, and how it runs the game, it runs the game for everyone and it's out of my hands.
That also solves the third problem I recently have had, which is time related. I just want to be able to pop in a disc, update (or buy digitally) and play. I don't really have the time to sit and tweak (which I actually enjoyed) or fix games (which can go burn in hell).
