I do enjoy game mechanics that interact in emergent ways that weren’t fully planned out by the developer in games like Dwarf Fortress.

Roguelikes with the potential for broken builds.
Sometimes you find the perfect combo on your run and become an unstoppable force, but it doesn’t ruin the game because you finish your god-like run and next run you try to find another overpowered build.

I like most game mechanics to some extent. Creativity in combining game mechanics is key to making an outstanding game imo.

However, I don’t like things that force a time limit. I play games as an escape. I don’t like feeling stressed by a clock while I’m off the clock. These can be literal timed missions or things like a food/water meter. Escort missions also suck for similar reasons.

I think difficulty in a game should come from overcoming a foe, traversing harsh terrain, or solving a puzzle. If the game is hard because I have to stop what I’m doing to feed myself, or I have to rush to complete an objective on a timer, it just becomes work.

Peaceful exploration

Save anywhere

I like systems that allow for outrageous combos, whether unintentionally or by design. Roguelikes and roguelites usually have them, but it’s almost entirely luck based. Dynasty Warriors 8 allows for plenty of OP combos if you manage the right weapon attributes. Skyrim and its broken as fuck perfectly balanced enchanting + alchemy (or Morrowind’s even more perfectly balanced permanent fortify attribute magic)

All the stuff mentioned here with jiggle physics

I’m not that excited by deep skill trees or crafting or inventory management, lately i enjoy good movement, music, exploration, and story.

The movement in destiny 2 felt really good, similar games have it where you get momentum, dives, floating with warlock, etc. I think Titanfall 2 and borderlands 3 zane had similar really good feeling movement.

The exploration in pre planes EverQuest was great, fast travel limited to certain classes and levels, risky but faster travel routes in kunark, groups in overworld and dungeon areas, dangerous places to get to with high reward for the risk. Elder scrolls, dark souls/elden ring, and Zelda breath of the wild had similar feelings for me.

I don’t know the name of it, but I really enjoy the sort of gameplay where you roll up to an enemy compound or something, and then you just sort of chip away at it and cause chaos until it all falls apart.

The sort of thing you’d do in Farcry, where you’d snipe some dudes, plant traps, shoot the tiger cage so the tiger would get out and eat people etc.

Enemy ai that’s not stupid

Games with high mobility mechanics like titanfall, echo point nova, doom eternal, destiny 2 strand hunters.

I’m not sure if this counts as gameplay mechanics or rather narrative structure, but games like Outer Wilds, Fez, Tunic, where the exploration and discovery of the game is the end goal of playing the game, not just getting to the game’s end state.

I’m not sure if there’s an accepted term for these games, but I’ve always thought of them as “archaeology” games. There’s a bunch of stuff, both plot and gameplay, that is hidden (sometimes in plain sight), until you discover it and find out what meaning it carries.

I really like Zelda and Ys style ARPGs. Specifically, rare and impactful loot, and little reliance on skill levels, but rather skill aquisition. Both approach it very differently, and later Ys games fall into more traditional RPG mechanics (e.g. farm money/exp, buy gear, etc), so I’m more talking about Ys 1, 2, and Origin, as well as pre-BOTW Zelda games.

Basically, I love this gameplay loop:

1. Enter dungeon/level and fight baddies
2. Find important item/ability
3. Use important item/ability to defeat monsters
4. Fight boss, using a mix of important item and learning movesets
5. Repeat 1-4 several times, with plot mixed in
6. Fight final boss using a mix of everything acquired

Ys and Zelda do this in very different ways, and I absolutely love the level cap in Ys 1 to enforce playing smarter instead of grinding. You can never really get OP, even if you try (except Ys 2, which I don’t like much).

Unfortunately, “ARPG” has been twisted to mean Diablo-like, which is heavy on loot and ability trees instead of puzzles and exploration, and future Ys games go that direction as well.

This isn’t really specific to mechanics or systems, but I’ll like pretty much any mechanic or system that lends itself well to that gameplay loop.

You know what I miss? The Ultimate Alliance games from the PS2 era. Isometric view. Build a four-person team of Marvel characters. Some team combinations grant group buffs, like having all four members of the Fantastic Four will increase your XP gain. Equip your characters. Pick from an array of comic canon costumes, each with their own abilities. Some combinations of equipment or costumes will also grant bonuses like having everyone wear their Age of Apocalypse costume.

The whole thing is an action RPG where you play through some big comic book crisis. Lots of opportunity for villain and hero interaction. Cool cinematics.

It’s a rock-solid platform, but I don’t feel like I see it used nearly enough. I remember playing an Ultimate Alliance on 360 and it just wasn’t as good; smaller roster, fewer costumes, less interesting in general, despite the better graphics.

I vaguely recall hearing something about one on the Switch and that Midnight Sons was a bit similar… but then again I don’t recall hearing much else about those games except for their existence, so they can’t have done very well.

The controls for the Skate games, especially 3, are great.

It’s easier to say what I don’t like. Open worlds and crafting mechanics, they are just so boring
