Just don't pre-order it... If you consider the game to be 'a buggy mess' (which is interesting, but bugs, like beauty, are generally in the eye of the beholder) why spend your money on something you hold such a low opinion of (unless, of course, you won't have the funds available until Q3 2021, which would make sense of your request...) until you are certain it will actually make things better for you?Dear Frontier Dev. Please don't make the same mistake as CD Projekt Red and Focus Home Interactive. Both game developers enticed me into a pre-order this year and both have released their games in a horrendous state. Because of these experiences, I won't pre-order your game but may buy it if initial reviews are good. If it's a buggy mess, and your base game kinda already is, I won't be buying it at all.
Here's your latest warning:
Cyberpunk 2077: Sony pulls game from PlayStation while Xbox offers refunds
I humbly suggest you go ahead and announce a delay until 3rd quarter 2021 and schedule an extra round of testing and bug fixing.
Just get it out there while the news cycle is demanding game developers do better.
I'm glad I have a powerful PC - Cyberpunk 2077 performs really well and looks amazing with some processing power behind it...
