Pay2win and Free to Pay games. Seriously, just charge full price for your game, or make it all free. TF2 does it right. You CAN Pay2Win, or you can wait for drops and stuff.
I like the free part for certain but allowing players to buy anything with real cash quickly destroys the games economy, I'd rather pay a monthly sub and see accounts that buy gold online banned, with no in game purchases like EverQuest used to be.
I've had this one game that pronounced Quicktime events as 'Clicktime' since it was a PC game. It was awful on just how they structured it. I cannot remember the game's name, but never again.
First-person jumping puzzles and ledge-walking are the bane of my existence. I think Yahtzee worded it the best: "[...] you essentially control a perfectly rectangular man with snowshoes on his feet."
I just think it's hard to control, and I personally find it annoying. I didn't say there was something wrong with putting it in a game. Chill.
I guess I misunderstood your tone. But seriously, my issues with first person and platforms is the reason why Portal took me that long. And Half-Life, for that matter.
Infinite re-spawning enemies Lives I dunno, those are just kinda bad in general, there is only one thing I truly hate about games and it's something that no developer should do. It's not really a mechanic but it's close enough. Games now seem to come with these day one passes and various other things that unlock parts of the game you purchased. These are not extra bits of the game that you get extra, these are parts that are on the disk and locked away if you don't have the day one pass. If you happen to not have the day one pass they charge you for that part of the game. The best example is Red Faction Armageddons destruction mode. This mode is locked to a 5 minute timer or something unless you use the day one pass. This is data on the disk and is part of the game I bought, they should not be locking these things. If you don't have the pass it is like 10 dollars for it to unlock which is bull crap. Another type of this is locking certain parts of the game with a required internet connection. AC 4 does this with Kenway's fleet, that is stupid. I am required to get online to access part of my game, I'm glad it sucks so I can ignore it. Would this ever happen to music and movies, would they really make it so that if you don't have a day one pass you can't watch or listen. Or locking out part of the songs or movie unless you connect online. It's stupid and makes me dislike developers that do this. I guess another similar thing to this would be rock$tar trying to get people to purchase their money cards after making like a billion dollar profit off their game. GTA 5 online was fun though repetitive, last I hear they knocked money in half after you do a mission. Which would be fine if money was easy to come buy, me and my brother did the same mission for over 5 hours just to get enough money to buy a penthouse with a blackboard spot to do a heist. Turns out they aren't even in the game at that point. It also makes me question how these heists would work. They already seem to want to cap the money earned and heists were the big money maker. I got another, games forcing you to play online to obtain somethings. GTA 5 makes me win online races to unlock certain car upgrades, no thank you. I can't stand the "people" that make up online gaming. So I get locked out of earning car parts unless I "boost" to get them. I can't think of any other examples then GTA 5, you have to kill other players to unlock gun colors, so I'll never get those. That's all I got.
Having to pay extra for multiplayer. I bought a WWE game through the Xbox Live Marketplace a while back, paid exactly what I would have paid for it in the store, and found out that I have to pay an extra ten bucks for online play because I don't have the code that comes with the disc.
I would have to say my most annoying game feature would be when they ship a code with the box which is then used to allow access to multiplayer. Meaning you have to buy a brand new version or download the pass online. EA as always is the main culprit behind this. They need to understand that what if it was a game that came out 5 or more months ago and so has been taken off the shelves? im not going to spend £15 to buy a microsoft points card to then use to only buy the pass to multiplayer which I could potentially only play every so often. Also I hate it when you make decisions throughout a game but it eventually counts to nothing therefor only your final choice matters.
random encounters in RPG's. The Tales series does it right at least. - - Auto Merge - - That, and Ubisoft's "U-play" system is completely superfluous.
Day One DLC. But, what should be a thing? Literal Day One DLC. Not the "pay money to unlock things on the disc" day one DLC, DLC you can purchase on Day One.
Day one patches....that's even worse... "okay here's your game. Btw, it won't work till you get the patch"
