What things in games just drive you fuckin' bonkers? Whether an aspect of gameplay, a technical limitation, or something the devs just decided to do. Here's some of mine, post as many as you've got.
Save points
It was more acceptable back in the day when RAM and processing power were at a premium, but nowadays, there's really no excuse. If there's gameplay reasons why you want to use specialized save points, allow the player to use an "interim save" so they can save, take a break, then come back without having to worry about which burning thing to save: their dinner or their character.
This was one of my biggest complaints with Skyward Sword. Every other Zelda game that I could think of, from the original on NES, to Twilight Princess before it, allowed you to save whenever you damn well pleased. (Even Majora's Mask after you get your ocarina back.) Suddenly SS decides "HEY! Save points is mo' bettah!"
Meaningless lives
Mario 1-up mushroom posted for being the most egregious example. There's no penalty for running out of lives in Mario games anymore, so why have them? They serve almost no purpose, and it's perfectlly normal to be able to get 3, 5, even 10 lives at once or more! Why not just do away with finite lives entirely and repurpose the 1-up mushroom as a free mid-level continue or something?
Note the word "meaningless." I have no problem with them if they're implemented well, such as in a challenge or survival mode in a game. But they're a trope of the past and should be left there.
UNSKIPPABLE LOGOS AND CUTSCENES
Sure, it may only be 30 seconds to get to the main menu, but that's 30 seconds of bullshit I have no choice but to sit through. If it were loading something, fine. But I know who made the game, I know you've got the standard deal with Nvidia to pimp their logo, you've got Speedtree, you've got Havok physics, I FUCKING GET IT. Just Cause 2 did it alright. They're only unskippable the first time. After that, it's two clicks and you're staring at the main menu; one more and you're back in game. Good design.
Unskippable cutscenes are not okay either, especially if you have to sit through several long ones before retrying an irritating segment.
I'll add more later, but I'm getting too worked up to avoid devolving into much more than angry ranting now. :P
