I just played Sea of Thieves on a really good PC. As a veteran of the game, i usually play xbox with mouse and keyboard.
To anyone calling PC being OP a myth, you could not be more wrong.
I could tell the difference. I could snipe players while on waves as i could compensare smoothly at 144fps, no oone could beat me in combat, could not be sunk as my loading times wese 2 sec, could just spam sword while staying behind my opponent at all times.
Certain things you can pull off on PC are simply impossible and incomprehensible on Xbox. My buddy said he will only play on PC cuz it's impossible to lose in the long run.
If I could afford a £2000 alienware gaming PC i would get one. In such a case, this came is pay to win. Just pay for a crazy PC and you have GOD mode on. Dont to mention drawing distance and other such things.
Dont tell methis is not a thing as i clearly have seen for myself. The difference is very noticeable. VERY.
Anything else are just excuses to protect PC players. Its an inside culture to deny all these claims so that they can keep their leverage.
My suggestion is, either remove crossplatform and reduce the amount of PC servers so that PC players are more concentrated, or limit the PC version of the ge to 30fps and same graphic specs as xbox.... Then it'll be fair.
