Oh dear… 
personnaly, I got 1,25 on a game but I’ve earned 24K out of it and it was theme hospital
and on game dev tycoon I got 2,75 and I’ve lost 200K
I know this is about the irony of GDT receiving low scores in its own game, but in my playthrough I lost 12 million dollars from a game with bad scores like this 
Is it possible to score a 1? Can you make the Action 52 of the Game Dev Tycoon universe?
I dunno, at least Action 52 had The Cheetahmen which at least had good music
