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

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

Not a game mechanics maybe but more of an engine thing i guess. I just love simulations. Good VR combat physics, elemental stuff like water, fire, smoke, crumbling stuff. I love a world that feels dynamic but not necessarily realistic that makes sense of itself.

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 help 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.

Detailed completionist checklists.

If I have cleared an area, I want to have it reflected in an overview screen.

If I’m missing an item, I want to know which enemy drops it, where I can find it, or how I can craft it.

If I need to pull out my phone to check a wiki, then the game has failed me.

There’s something to be said for exploration games, and in those cases, the details should be obscured until the player has cleared 90% of the area, or gotten past the boss (or something like this).

Dynamic skill leveling: maybe it’s not an actual stat with a number you can watch go up as you keep using a particular play style, but I like when games let you and your gear get stronger together the more you use them.

More floaty, less realistic platforming. Thugs like double jump, or somehow your character has less gravity when they jump, stuff like that. Stuff like that. As a general platformer lover, I really enjoy more fictional cannot be done IRL physics in games.

Among plenty of the other things mentioned, I enjoy “diagetic interfaces”. Ways of interacting with a game’s systems that stay grounded in the reality of the setting of the world. Dead Space is a prime example, but I’ve been enjoying a lot of the crafting in Vintage Story for this reason. The smithing in particular has had me hooked for a while. Hammering out my armor and weapons voxel by voxel made finally suiting up and feeling ready to take on a boss that much more satisfying.

Parry and riposte mechanics make me happy. Idk why exactly, but something about timing a parry and making the enemy entirely helpless for the followup is just great.

Hard to learn complex mechanics in simulation, such as target management analysis in dangerous waters, any of the jobs in space station 13, eve online

Roguelikes and roguelites tend to be my favorite. Ones where each run is new and you can toy with different builds and usually get pretty OP toward the end (or get cut down early because luck wasn’t in your favor or you made a mistake).

Inventory Tetris

I love anything with a tech tree or a skill tree or items that improve based on usage. The ratchet and clank games have such a great mix of all of those things, I end up spending a bunch of time just leveling up the guns!

Intricate character building with multi-class synergies. Is. My. Shiiiiiit!

Small wonder I love BG3 and Owlcat’s Pathfinder games.

Puzzles, traditional or unique, as well as physics and spatial-heavy thinking.
