C&C - I've never even made it through a single match. The amount of effort it took to force myself and get as far as I did was way more than necessary.
Skyrim - I tried, even installed the mods but this level of sorcery and amount of dialogue just kill the action crave I need.
DayZ - I just don't understand how people have hours upon hours of time to spend on a single session to play this mod. Not to mention bugs like loosing phenomenal guns because you didn't switch correctly, breaking a leg from skipping two steps, loosing a fully kitted gun jeep because you touched a wall, etc. I understand ARMA is reknown for it's detail but I just can't find the fun in finding a can of food on the floor, or getting too cold so needing an axe with wood plus matches, etc. Plus the endless running through woods for hours without a single bit of action is soul sapping. How can anyone deem these as fulfilling entertainment? I guess I just can't justify doing all that for hours to finally get some genuinely nerving action (and I put in 5 hours with a large group of friends).
I guess my time gaming on the PC is at an absolute premium and if there isn't engaging action within 10 minutes of play then I have about 5 other games installed that provide it readily.
