Do you think skins really affect the gameplay?

I don't think so, specially on CS:GO, maybe if we were talking about valorant

No ablolutly not. Its just a preferance

it's only psychological, but I feel like I have more motivation with skins and therefore I play better

The character model skins are a HUGE problem but noone wants to talk about that...

Not really, a skin is just a skin. Your skill in the other hand.. that might be something else

Depends. Weapon skins or player skins?

How would a skin affect your gameplay lol

no in cs go this thing do happen like in league of legends or something

not the gameplay but how you might perceive your skill
some people think they play better when they have skins on so they automatically tend to play a bit better
