A lot of it is untracked, though. I know we live in the era of big data, but Blizzard et al has no clue how many people are playing TIE Fighter Total Conversion and countless other old games. 5% is way too low of a made up estimate.

Hell, classic arcade emulators are ubiquitous.

My point here is not that game publishers aren’t making money. My point is, gamers don’t have to buy into it to have fun.
