As the title says, are there any gaming challenges you hate doing but feel compelled to complete because if you don't then you'll be unhappy because it is incomplete? I ask this because I am at the moment going through CoD Black Ops on Veteran difficulty. I hate the story of Black Ops, it's ridiculous taking place from 61 through to around 80 - 85. Doing it on Veteran means I will be redoing sections of the game over, over and over again until I finally either shoot myself, destroy my 360 or else otherwise go insane with rage at it. However considering I am now fighting my way through Vietnam having just gotten past Hue city escape scene I will say I find myself intrinsically drawn to the fact that now I have begun to play the game on it's hardest settings I must continue on with it until I complete it on the hardest settings.
One thing I find ridiculous with this amongst others is that Treyarch force a certain style of gun play to the fore. In CoD's MW series enemies are finite in any area. Sure there may be a ton of them but they will eventually cease to spawn, though if there is a time limit on the mission taking the time to let this occur is often impossible on the higher settings (here's looking at you CoD 4 storm the nuclear silo in 10 minutes on Veteran) In Black Ops there are certain points of the game (there is a corridor on Executive Order and the hill at Khe Sangh for example) where the enemies spawn infinite times. This is annoying as my general style of play seems to be the cautious type for the most part only performing rush attacks if the mission absolutely calls for it so sitting back, picking off enemies and whitling their numbers down is my style but Treyarch make it impossible to do so.
I hate this challenge but I can't stop doing it to myself!
So as a topic, share your own gaming experiences where it isn't always fun but you're unable to quit on it.
