In RPGs, I pretty much always play rogues, and I like being the tricky, fast, stabbity sort, so double daggers are my go-to.
In shooters, I like semi-automatic/burst rifles with little recoil, a decently large magazine, and a relatively speedy rate of fire. The BR/DMR from Halo is pretty much my golden standard.
Oh hell yeah! I loved using the Flak Cannon in Unreal Tournament and playing as the Demo Man in TF2.
Hugging, and if that’s not available, shotguns baybee
Melee: Two handed swords. The claymore from Dark Souls is my favorite, but some of the greatswords are good fun.
Firearms: Machine guns, always. Most games don’t have have a suppression mechanic, but I love having 100-200 rounds to shoot at any given time.
Give me the AK-47 every time!
Not the most accurate or fastest rate of fire but it hits hard, makes a lot of noise and has that sexy wood grain.
In melee I’ll take a spear.
In Monster Hunter I only ever use lances. I won’t even try the others. I also used lances/spears in the Rune Factory games.
I don’t play a lot of games with weapon choices but I guess I like lances.
That wooden “clack” sound is always satisfying when done well.
I love any kind of dual wielding but mostly daggers? Bows are also chill. (I’m rogue trash can you tell).
Bow and arrow for every situation. something really satisfying about compensating for drop, and having an arrow sticking out of your kill. Also reuseable ammo is a big win.
Even though light and quick is clearly more my style I often end up using big axes and hammers because swords are so boring. I don’t know, I’m hipster trash and, urgh, like, swords are so mainstream, you know.
Depending on the game swinging around a big hammer can be a lot of fun (or, maybe there are one-handed hammers and things, in which case, PERFECT), but it’s about 50/50, sometimes I’m not good enough at the game to competently use a strong, slow weapon, and end up with a sword anyway.
I love spears, but they’re less common.
Bows are good, sometimes, but sometimes I hate them? Very much depends on the game.
I’ve started playing kingdoms of amalur and hey, more games should give you chakram, in my opinions. They frickin rule, I’m having a great time.
Bows and shortsword/dagger. rogue supremacy.
A good semi-auto rifle is my favorite weapon of choice, and the M1 is my personal GOAT.
I also love railguns or anything that requires a small charge up time.
Melee, I’d rather use my fists or some kind of fist weapons.
I like big hammers, clubs and maces. They’e often inaccurate and clumsy to use but incredibly satisfying when the hit lands.
Though lately I’ve been getting a magic itch, so I’ve been going for whatever witch/wizard option the game offers.
I like to use weapons that don’t require much aiming. Shotguns? Check. Explosives? Check. Giant Swords? Check. A magick bow that locks on to enemies? Check. A plasma gun that shoots a 2ft wide projectile? Check. Any sort of dialogue system that allows me to talk my way out of conflict? Check.
Mostly that sort of thing.
Mines! Proximity, trip wire, timed. I’ll take 'em all. If mines are unavailable, large quantities of grenades will sometimes do. (I was banned from using mines in Timesplitters)
For low tech RPG settings I gravitate to bow and axe. Good solid peasant weapons. Maybe you want to fight some dudes or maybe just hunt your dinner and chop up some wood to cook it with.
I feel like across all games shotguns are usually a pretty safe bet that very satisfying ch-chunk of the pump action goes a long way.
there is also a part of me that is always drawn to sniper rifles although I don’t have the cool head or aim to back it up most of the time. my ultimate is sniper rifles in a tactics game like X-com or Valkyria Chronicles. thos guys always become my favourites. I once plugged an alien through a doorway from a balcony on the other side of the room in X-com and it was truly my finest moment.
I like how a few of you already brought up the satisfying sound of certain weapons. That definitely counts! 
Me, I dig the sound of reloading a bolt action rifle. Especially if it’s also animated properly.
It depends on the game, but generally, in a shooter I like to go for a shotgun. I don’t necessarily enjoy having to get up in people’s faces to be effective but shotguns pack a punch that I feel like I never really get with other weapons. Sniper rifles are close, but they’re often super unwieldy. Sometimes pistols also fill this niche, and if the shotgun is bad I’ll try and make the pistol work. And automatic guns are always just. Boring. Really really boring.
For melee I change between liking single handed-swords or sabres, preferably with no shield, and straight up unarmed melee. Two-handed swords often feel really clunky to me, and I don’t really like the micromanagement of trying to block with a shield.
Also if it’s a game where a bow or crossbow is an option I will def go with that.
As a general rule, if the game at any point says to you “this probably isn’t the best idea” I’ll kick arse with it. I’m extremely good at taking advantage of the small psychological effects that come from using lesser-known weapons. Greatshields and Whips in particular, in Dark Souls terms. Though anything with an element of baiting and/or manipulation I can make work.
If we’re talking real life though, I’ve practice with a staff to an extent, do in a pinch I’d rather be with something like that.
