I am kind of disappointed how Flash has grown next to pointless in the overworld except for maybe one or two locations... remember how it was an HM once?
In Black 2/White 2, the thing that drives me crazy is the lack of auto-sorting of items like TMs, HMs, and Berries. In past gens, items like TMs/HMs and Berries would be auto-sorted automatically as soon as you obtain them. However, now in Black 2/White 2, that feature seems to be gone. TMs, HMs, and Berries now have to be manually sorted, since they appear in the order you obtained them, not numerical or whatnot. I know there is a easy way of doing it, just hit start and then select the type of sorting design you want, but since past gens would automatically do that for you, why did that feature disappear? I'm a guy who likes to be (or at least tries) to be organized, so that automatic sorting of those items was a nice perk. So why did it not make a comeback in B2W2, especially since BW had that feature?
The part of the game where you don't have running shoes, and you have to walk to and fro, to and fro, and I'm just like "AGGHHHHH GODDAMNIT WALK FASTER DAMN YOU". "orz
Not being able to fly directly from Kanto to Johto and viceversa without having to stop at Indigo Plateau before in Gold/Silver/Crystal/HeartGold/SoulSilver.
i think what irks me most is that a lot of the newer games seem to have a lot of features reliant on you having local friends with the new games as well. ever since i moved out of college, i literally have no one local to play with and all i can do is turn my cgear on in the car and hope for passerbys.
One of the most annoying things is that in every game starting with FR/LG, whenever you lose a battle, you are forced to watch a cut scene in which the player is healing his Pokemon at the last Pokemon center he was at, when in previous games, you just got warped to the front entrance of the Pokemon Center and can just move on from there without having to talk to the nurse at all. I find this to be unnecessary and annoying, and there's no way to avoid it.
Another thing that annoys me is the high encounter rates in caves, I always come prepared when entering a cave by buying as many Repels as I can, just to get to where I need to go faster.
another thing that pretty much goes without saying, HM moves. Ruining good movesets since gen i, and back then there wasn't a such thing as a move deleter, you taught your starter a useless hm move, you're stuck with it. Let me teach my best pokemon flash or brick break real quick JUST so I can get through this dungeon. And just now playing platinum, defog is the stupidest thing ever. I can still see so I didn't need it except to get some useless tags (well, unless there's something down the line I have to use it for)
I hate that the rate of Pokémon hitting themselves when confused is 50%. It's too fucking unfair. It should be lowered to 30%-35% or something like that.
Another vote for HM moves. It almost seems like Game Freak deliberately programmed them to be as annoying as possible. You can't unlearn them until you've passed a significant chunk of the game (and not at all in gen 1), most of them are only useful for their field effects (aside from Surf and Waterfall of course), and as I found out the hard way when transferring my Gen 4 teams forward the other day, you can't trade or transfer any Pokemon with an HM move (seriously, if you don't want me using the move yet, just go back to the "get badge, get field effect" system)
Why in the hell am I not able to buy Coins at the Game Corner in HeartGold?!?! I NEED to buy Ice Beam and I will never reach 10.000 Coins playing Voltorb Flip! That game sucks! Let me buy my Coins if I want, Game Freak >:( Or put the Game Corner as it used to be; the entire world doesn't have to pay for a law that only applies in Europe!
I just thought of another thing while trying to farm money in Black 2: the fact that you can only sell one item at a time to Item Maniacs. I guess they did it just to give item maniacs a downside compared to Poke Marts, but it's still a bit annoying having to sell my 30 Lava Cookies one at a time for 4000 a pop.
The HM Defog could ATLEAST get an upgrade- perhaps an alternate Haze or something. Or maybe decrease something else with the evasiveness stat against the opponent, such as lowers Speed and Evasiveness.. I dunno. The uselessness of that move annoys me. : U
The little bump noise when you hit something is pretty amusing. :"D Except when you're trying to get into a building with a bike. Or maybe an NPC who moves constantly keeps moving infront of you. WHY.
Something that hasn't really irked me before, but now has gotten extremely annoying since I started both Black and White again at the same time the other day:
How much the damn professor talks. I mean, seriously. Do we really need a 5-minute explanation as to what the hell Pokemon are and what your purpose in the world is? I just want to play my game, damn it.
