I have a couple of quirks that I've noticed:
- I play games for hours at a time, but am only capable of playing well for +/- an hour. This is very noticeable with MOBAs. I'm also terrible at games when I'm on voice with people, drastically reducing my skills and making a fool out of myself.
- I seem to be unable to finish most games nowadays. A game like The Last Guardian has my attention for about 2 hours, after that it feels like the game has shown all it has and I lose interest.
- I never ever care about aesthetics. If it's relatively workable, I'll be able to deal with this. I've noticed my friends grunt in frustration when viewing my base in Rimworld for example. I'm not bothered with the chaos.
- If there's a summoner/pet class, I will play it. Bonus points if it's a Necromancer. More bonus points if you can summon/control multiple units.
- I will miss out on every single collectible in the game, unless it forces itself into my throat (mini map markers and stuff).
- If I get the chance to fight a boss early and there's a minute chance I can win this, I'll usually try it over and over and over. There's a martial artist boss like thing in NIER:automata that keeps getting stronger when you defeat him. I think his highest level was around 85 or 90, I beat him with my level 20 character.
- When playing games with a meta, I tend to go straight against it. It fails 9 out of 10 times, but that 10% chance of success is hilarious. An example is AD Carry Soraka back before her first rework. It worked so incredibly well. AP Sion before rework was another thing that worked out pretty well, but that one was more common than AD Soraka.
