1) Random encounters in puzzle rooms. When I'm trying to concentrate on a puzzle, I shouldn't get into battles because it breaks my concentration. An offshoot of that is Tower of Babel in Xenogears where I would get into a random encounter MID-JUMP in one of the most horrifically broken and twiddly platforming sections in a traditional RPG.
I actually
finally got to that part of xenodurr today
i feel like those things in games that charge up by doing damage or getting damaged (like overdrive in ff10) are worn out
and I didn't really notice it while i played it, but someone recently mentioned in one of these threads that enemies in ff8 level up with party members (inconveniently making unused characters almost impossible to survive against that final boss)
and that's something else i hate about some games, not all inactive members get experience and they become too weak
too frequently random battles, respawning enemies (especially in persona 3 and ff12) and massive amounts of enemies in one area all really suck
some games, ff12 in particular, make me wait to long for things like summons and magic to take effect even if it should be already done once it starts and by that time I may be dead
I hate that most games have way too many npc's and don't let me know if they something new to tell me
and also weapons that break are slightly annoying but I liked that dark cloud 2 used that and actually made it fun in a way
edit: I also
hate those thing that force me to work on a puzzle for hours to move on or get a crappy prize and and games that have too many battles and always give too little experience, such as legend of dragoon
