Yeah, well.
I think that, to some extent, I do understand where you're coming from. However, I am also quite certain that you are simply 'not getting it' when it comes to GTA.
I, too, intended to hold off until it would eventually be released on PC. However, my resistance fell after ten days, and I haven't played anything but GTA V (finished the story) and then GTA V Online all the way. My buddy list on the console has exploded and I'm freelancing for four crews beside working on establishing a brand for my own, strictly one-person crew (it's all about me after all).
I have Davros Cäge's latest oeuvre, Beyond: Two Souls lying around, waiting to be experienced. I just can't be arsed. Every minute I would 'play' Beyond would be a minute lost in GTA V Online.
Yes, you are right that The Last Of Us will still be there once you decide to go get it - if your console is still working by then. With GTA V, I absolutely have to disagree. The short but very meandering and bumpy road from the initial release to patch 1.04 was something you just missed out on. There is no way to get that back. And I personally consider that to be a rather sad thing. You haven't found your favourite activity in the game yet. You've never found a glitch. You've never made a million or two. You've never bought your toon a nice home. You've never had a bounty set on your head and then spent the day watching silly people kill each other trying to kill you, which of course they can't when you're just watching them from inside the comfy confines of your not so humble abode.
And you don't know about the feature that lets you watch some random dude play GTA V on your TV all day long, sitting on your couch. Just when it gets boring and he gets the upper hand, send mercenaries after him and watch him die on TV. Oh the humanity.
So, yeah, in regards to the single player story/campaign mode, you're just not in the loop about what all these random folks on the internet are blabbering and opining on about. But in regards to the rather fresh online launch, deciding not to be a part of it is a bit of a bummer. Then again, you have more spare time to do other things, as GTA V Online happens to be quite addictive.
