Borderlands 2 for me. Felt like I died far too often in the game and not in any sort of fun way. I don't mind dying or losing if the game feels like it's doling out tough love fairly (something like Super Meat Boy comes to mind), but so many times I'd get just mowed down far too fast. If I wanted to go in close with a shotty or something else, I'd end up fairly often in a constant Second Wind-knockdown-Second Wind-rinse repeat cycle til the game decided to punish me for using the mechanic too much and shorten the timer on it. Which hell, that whole Second Wind bit confused me/drove me nuts. It was a neat "second chance" mechanic in the first, but in this one I got knocked down 100x more than the first, and in this one so many times as soon as they'd kill me enemies would run the fuck away so I couldn't have a chance to kill em again! Well wtf! Why even have that in there if your AI is gonna be a dick? I even started noticing, granted this is anecdotal, that they'd run away and not expose themselves to me until like 1/2 a second before I'd respawn and they'd always jump right back out then, just kinda pouring salt in the wound!
The AI in general seems kinda idiotic...too many suicide-type enemies (seriously, between these and escort missions I don't know what oft-reoccurring elements in games I hate the most), so many enemies like basic Psychos and whatnot that just come right at you with little regard for their own safety. Just rush up to you most of the time, then run away when you're down half the time. If I didn't just stand back with a corrosive sniper for the last half of the game I would have lost my mind. In general, this entire game seems designed to reward people for just bitching out, sniping behind rocks. Well that's fine and good if there's a limited number of enemies...but when I fight the same enemies again and again and again and again, I just can't be bothered...I just want to mow them down to speed up the monotony. Could completely have been just bad luck with what weapons I ended up getting, since I do know there were many times I'd get a gun that just outclassed my current one by 3-5x and would make a section much easier. Guess that's kind of a potential hiccup with games that have random/semi-random elements.
I probably just wasn't ready for another Borderlands experience anyhow, having played through the game and all the DLC recently for a second time on PC. Can't say Blands 2 is objectively bad, just not for me at the time and lots of elements to it seem half baked. Which is a weird complaint considering how many little neat bits there are that show a great attention to detail overall.
