What do you mean? How many games have yet to receive the "internal installer update" treatment? If so, and according to my records, 439 games have had an internal installer update so far (this includes several removed games).
InkPanther: Do you have an estimate of how many of those installer-only updates are left, by any chance?
I've got no idea how many of the current 2561 products on GOG catalogue are "base games" (i.e. not DLCs). Within Legacy MaGog's scope, 1768 out of 2171 catalogue entries are "base games": that's a 81.4%. Assuming the percentage of non-DLCs has remained the same since MaGog stopped tracking GOG products, the number of "base games" must be somewhere around 2086.
That means that there are still about 2086 - 439 = 1647 potential "internal installer updates" remaining.
