Oh indeed, I'm sure I'll be complaining about it at some point
Some interesting non-spoiler but sill a bit spoilery facts that might be of interest to some:
45 of the top 50 games were indeed present on the previous regular Game of the Year results:
The top 2 and no's 4, 5, 10 from 2010
The top 3 and no.5 from 2011
The top 4 from 2012
No.1 from 2013
The top 6 and no.9 from 2014
The top 7 from 2015
The top 3 and no's 5, 8 from 2016
The top 4 from 2017
The top 5 from 2018
The top 3 from 2019
So we could have just pitted all the previous No.1s against each other, but then four of these previous number ones all tied at 29th, meaning that there were about 30 games that the watch liked more, so that wouldn't have been very accurate.
We could have just pooled all the top 3 games, and this would have been a lot more accurate as only three top 3 games failed to make the list: Divinity 2 DKS/FOV , Expeditions Conquistador, Baldur's Gate 2 EE, however, again, for several of the years the second or third spot only garnered a bottom of the list place, with none of the 2016 or 2019 games placing higher than 24th.
We could have just pooled the top 5 games from each year and this would have just about done it… well… if you consider 80% to be just about. 11 games that made the top 50 did not rank higher than 6th in previous Game of the Year polls while nine previous top 5s have been thoroughly forgotten about. The highest placed non-top 5'er made a respectable 18th place, so it would have been very harsh on some games to exclude them by using this method.
And then there's the five games that were never placed on any previous GOTY polls which, admittedly, do not place very highly here, the highest placed one being 24th, but no doubt will make a large number of people very happy by their cumulative inclusions.
