Again, you state numbers and opinions which you have no data to support your belief and yet you call sophistry on my comments.
Very well, allow me to provide proof. (something you will never do)
According to my F95 games directory I am playing 289 games downloaded from F95. I have tried some more which I deleted the folder of after downloading.
Of those 289 games, 1 of which breaks the save game every single version.
taffy tales = 6 releases in last 2 years all had this issue. Moreover there is not even an attempt to import them, we are flat out told it is incompatible. I had tried transplanting them before, it detected them as old saves and refused to try to load them.
4 games of 289 break saves frequently enough for me to complain about in my review. But not every single update.
wizards adventure
witch hunter
haremon
witch hunter trainer
1 out of 289 = 0.34%
that means 99.66% of games manage to not break your save every time (actually even higher than that, due to the deleted games).
As 99.66% is indeed greater than 99% my claim that 99%+ of games manage to not delete your save every single time is correct.
Thus your claim that early access games cannot be expected to, as a matter of policy, not delete your save files every single update. Is the height of sophistry. As 99.66% of games do not do it.
Note that the 1.24% of games that have frequent enough save breaking that I complain differ in that they at least make the attempt to import your save between versions. And often even do so successfully. They just have a failure rate high enough to have bothered me in their attempt at importing old saves.
