All characters come with three perks (teachables) that can be unlocked for other characters when prestiging them (after level 50). Killers also have a unique powers.

Indeed some killers are less popular, right now one of the most hated ones is Skull Merchant. She was highly problematic and already got a rework but still most people don’t like her. Knight is another killer who doesn’t get much love.

Other than those, there are always people who like or don’t like to play against certain killers. Often it’s more a matter of how they are played and in some cases how good they are - a top tier Nurse or Blight can be miserable to play against, but I find a „normal“ Blight pretty fun face. Same for Nurse though a „decent“ Nurse is tough to find. Most are either bad and you can run circles around them, or Godlike.

You can play with/against anyone, in public as well as private matches, they don’t have to own the same character.

The first adventure game I bought and played was an Infocom interactive fiction … I think it was Stationfall. Before I had briefly played Magnetic Scrolls’ Fish! at someone else’s computer. Fell in love with text adventures and started collecting them, I have a few of the Infocom folios as well (sadly not the Starcross saucer). The first graphic adventure I remember playing was King’s Quest IV.

These games, along with later games like Monkey Island, had a huge influence on me, I learned programming to write adventure games myself but spent more time writing adventure game engines (both text and graphic ones) than actual games, and today I’m a software engineer (not in the game business).
