So an instant killer of my opinion of any game ever made is poor camera angles and having little to no ability to do anything about it. Being someone whose eyes don't handle working in three dimensions very well as it is, a poor camera severely hurts my ability to enjoy a game, and as such I've gained some notoriety among a lot of people for hating games many people otherwise loved.
Most egregiously I was playing Super Mario Galaxy on my friend's Wii some time ago. Thirty seconds after landing on my first planet, I asked how to adjust the camera after pressing several buttons and finding that nothing worked (and a crossed out camera icon kept appearing on the screen; I couldn't see where I was going because the angle had gone perfectly overhead so I couldn't see how deep anything was.) His answer: "you can't." My response: turning off the Wii and swearing never to play the game again.
I gave the original Devil May Cry very similar treatment as well, and when a friend of mine was playing one of the later games I noticed it hadn't improved. Said friend was a games design student and remarked that camera control is very difficult to do.
Another incident occurred when I was watching someone play one of the Space Channel 5 games. In that you have to follow directions... but in one round he had to follow the directions with the camera constantly cutting to different angles so you couldn't actually see what direction the character was moving to copy them. After he failed the sequence several times, I told him to turn off the game and refuse to put up with it, and I ranted for fifteen minutes how disgusted I was that the camera had hindered a freakin' rhythm game, one of the simplest genres on the planet.
How do you people feel about bad cameras in games? Personally I don't think there is any excuse for them whatsoever; these people are paid professionals and I expect a professional job for something costing upwards of forty quid. If your game's camera is bad, there had better be something goddamn special about it to make me not turn it off in disgust.
