Which SciFi ttrpg has the largest player base?

I notice no one has mentioned Alternity. Granted, its first edition has been dead as long as TSR, but I know it had a kickstarter new edition in the last few years (as my brother got it), but never seen anyone playing it.

2e's come out, and pretty much gone unnoticed. It's a shame, as a crunchy but not overly heavy generic SF it's actually pretty decent, and levelled but classless is the least common way to do an RPG.

But it's nothing special, Protostar seems to be pretty generic, and the more out there Dark Nebula might be too close conceptually to Fading Suns. It's not bad, it's incredibly solid, but there's not a ton going for it. Even a decent 'build an alien PC race' system would have helped it.
