More specific to a single game than a general problem with games, but the enemy spawners from Rune Factory: Oceans are easily the most bullshit thing I've ever had to deal with in a game.
You'll be in many situations where you'll be trapped in a room in a dungeon and in order to progress you need to clear the room. There will be monster spawners in that room, normally more than one, and as long as they're there enemies will endlessly spawn. So fighting the enemies is entirely pointless, you should be focusing all of your attacks on the spawners.
Problem is, every time an enemy attacks you you're knocked down for a few seconds which interrupts your attacks. As well as that, the game has no dodge, so essentially if an enemy within melee range tries to hit you, it will. As well as that using healing items (food, potions etc) takes a few seconds while you go through the eating/drinking animation, and if you're hit/knocked down while using it, it's interrupted. As well as that, enemy spawners take a lot of hits to destroy.
So what does all this add up to? You'll be standing in front of an enemy spawner and smashing square because that's all you can feasibly do. Within a few seconds you'll have dozens of enemies in a big crowd around you continuously knocking you down, knocking you down, knocking you down. You'll be able to get one or two hits inbetween each knockdown where you can hit the monster spawner before enemies hit you again. Now you've been hit so much that you're low on health and about to die, and because you're surrounded by enemies you can't run away to use a health item elsewhere, so you have to use it and pray to the gods above that no enemies hit you while you're trying to use it. If they do, you have to wait a few seconds for your dude to stand up then try again, and repeat this process until either you successfully use this healing item or you die.
Repeat this several times per floor per dungeon and you basically have the entire mid-to-endgame experience of Rune Factory: Oceans in a nutshell. It is not a fun game. And to add insult to injury when you finally get through all that shit and beat the game and get to the postgame which if you're into that sort of game is where everything you're playing the damn game for is, the game's localisation just melts into shit and the voice lines are full of editing errors where you can hear the voice actors talking to the director, the text is full of typos, the voice lines and text often don't match, notes the localisation team left for themselves in the dialogue boxes to come back to later are left in, and other things I can't remember.
In postgame I finally got to marry the character I'd been going for since the start of the game and if you marry that character their voice line that they use every time you greet them becomes one where the sound byte begins with the voice actress talking to the director in her normal voice and preparing for her line. "Okay. *mhm* (pause) "Hello, what is it?""
This game came out 7 years ago and there has not been a single patch addressing any of this since. It's like they knew how bullshit the game was and assumed no-one would get that far so they didn't bother finishing the localisation.
This has been a tangent but I'm mad. Game sucks. Don't buy it.
