Sure, you just twist everything I say.
With the numbers we have you can make a very rough guess based on rough numbers. Bottom line is, if the game was 20/80, then it sold all it's 150k copies in the first day and sold nothing else for the rest of the week.
Variables which can skew the workings:
- Average game cost for the units sold in revenue
- How much was spent on micro transactions, or whether they got included at all.
- Special editions, based on the volume sold compared to normal variants, this could drag this average price per game up
EDIT: I'll put the workings here again just so people can see.
Revenue: 7.7mil in the first day
Average cost per game: £41
Physical copies sold in a week: 150,000
7,700,000/41 = 187,804 copies sold in the first day
20/80 split physical/digital
187,804 x 0.8 (80%) = 150,243 physical copies sold in the first day
So yeah... doesn't add up at 20/80.
