The Chinese Starfield leaker has finished the game and provided credits as evidence, he says it's an 11/10, Lol. The main Reddit leaker who has been providing evidence of having the game replied to it and said "Indeed" At under 10 hours of gameplay he said it wasn't a GOTY contender but still great, at over 20 hours he said it was a GOTY contender, so like all leakers have been saying, it is indeed a slow start but rapidly ramps up a little later.
Another leaker who is playing on PC said it's easily a 9.5 or 10.
"I'd be surprised if it's not in the high 80s or 90s. Bethesda cooked with this one. Space part is great, but again I think expectations were though the roof. If you liked what you saw in the direct and enjoyed past Bethesda games idk why you'd be worried. Subreddit has been overhyping on some areas. the majority will be very happy Imo, it's a great game. the sheer number of options and freedom to create your own path is fantastic"
