TARFU: Ok, let's say you purchase a game and then complete it and view all extra content available (manual, etc).
Do most of you uninstall/gift the game, or do you keep it around based on how much replay value/nostalgia it has?
I uninstall it, because I'm not a completionist and I'm not seeking 100% on achievement and things like that. I keep it installed only if it has a multiplayer component and I know I can play with my friends. Otherwise, if it has multiplayer and none of my friends play that game, it gets deleted as well...
I just finished
Paranormal State: Poison Springs, a HOG I certainly got in a bundle because I don't remember paying for it specifically.
Good HOG overall. The story is nothing original but still gets the job done. Hidden objects sequences are well done and require a bit of thinking, which is nice. But the characters are quite badly drawn, I think, a bit like a mockery of american police dramas like CSI or the likes. But it is still okay.
So, well, yes, a nice game which will take you around 5 hours to complete if you have the collectors edition which seems to add a chapter after the end of the game, a bit more if you want all achivements maybe. If you like HOG, it's quite a good game.
And while I was at it, I played
The Stanley Parable. Played and not finished? Yeah, because, well, I've played a handful of back-to-back runs, different endings and thus I finally consider it as finished and uninstalled from my computer. Why? While enjoyable and making me astonished at the cleverness of its authors, it still tries too hard to be deep for me. And I have other games to play. So, I didn't hate that game, but it failed at making me wanting to play more.
So far in 2015:
