I have a high tolerance for mediocre video games..I normally see everything through to the credits. I think it comes through years of being a 'trophy hunter', which I have now thankfully left in the past.
I can think of one game I played and stopped because I was bored, and that was because it was the first graphic novel I had tried, a genre I will never bother with again.
What I do have a low tolerance for is games I simply can not finish, and this falls into two categories:
1) Horror games. I love the story and vibe of most horror games, but I just get way to stressed out playing them. I barely ever finish them. Resident Evil, Evil Within, Silent Hills...I've tried them all with no success. Metro or Bioshock are about my limit.
2) Metroidvania / platformers. I really struggle with a lot of these games due to a lack of skill and can very rarely get far in them.
I have two cases in point from this weekend actually:
First I tried Axiom Verge, and spent about an hour trying to get past the second boss. Then I read online that this should be child's play compared to the latter bosses, which are much harder. So I think, what's the point? I'm never going to finish the game!
Later the same day, I tried Resident Evil 7. Good grief! About an hour in and I shut that down and never want to play it again. Way, way too scary!
In both cases, I really liked the game, but will never finish it.
This leads me to an interesting question. I only started a collection very recently, with the aim of building a library of games I have beaten in the past or will beat in the future. Technically, as I know 100% I will never beat them, I should trade them in. But I do like the games and cover art. Decisions, decisions...
