Starfield is currently a 4-5/10 game and by the time Modders will be done with it, probably a 9/10 game (10/10 if someone mods the whole main story out of the game).
But that's not what modders should be wasting their time on. They shouldn't be fixing the game.
Besides, the changes and oversimplifications Bethesda has made to the engine and the extraordinary announcement that the modkit will take a year to be released, will vastly delay the amount and quality of mods that will be released for the game.
Baldur's Gate was a 7/10 game on release, mostly due to the issues with Act 3. But they took all of a few weeks to fix the vast majority of major issues and bring the game upto 9/10. Every patch and hotfix they released fixed thousands of small and large issues.
Meanwhile Bethesda announced updates right after the game released, fixed like 4 progression breaking bugs and nothing else.
10 days after announcing they were working on bugfixes and patches, not a goddamn peep, not a single thing fixed beyond those 4 small fixes.
It's straight up disgusting how these corporations operate.
