Gaming

QTE by far

Open worlds with markers. It takes every feel of exploration from me and changes the open world part of the game to really long and boring interactive loading screen through which I must pass between (very often) very linear missions.

Those hints to success "difficult parts". Some games think their players are braindead. If you have some trouble or spend a bit too much time doing a quest or killing a boss, NPCs or game interface constantly yells at us hints to skip those "difficult" parts. Games are more and more aimed for dumb casuals. I'd rather have the satisfaction completing a challenge by myself. Lets not forgot that today's games are increasingly easier and shorter (and pricier) than before...

Fast travel that is just a game mechanic with no story ties in open world games.

Disclaimer: My main experience with games so far has been some Nintendo stuff, Fallout, and The Elder Scrolls.

Of what I've played I like Morrowind's fast travel system the most. You don't just open your map and click a button, you talk to people or use a spell/item. And NPCs mention these travel systems and story wise would use them.

I like Oblivion's (and to a lesser extent, Skyrim and the 3D Fallout's) the least. Time passes like your character walked to where you fast traveled but not much is timed so that has little effect on immersion. Too much of the journey has to have gaps filled in by the player's imagination because walking on the road normally has a lot of encounters and wandering off to check out random buildings and people. It encourages less exploration and taking some time with the game.

Obviously I want a balance, I don't want to be walking the same road with 2 wolf encounters a thousand times because it's between two areas I need to frequent. And I don't want 90% of my playtime to be traveling. But I also don't want to keep instantly fast traveling to all places and feel "lazy" and like I'm missing experiences and encounters. And I want more immersion. More character interaction instead of UI interaction.

When you enter a level and the camera pans over every important thing in the level before you can move. I'm not an idiot. I can discover the level on my own. Stop holding my hand.

Pokemon-style puzzles and crafting.

Anything where the player is essentially a superhero, I like summers though...
