Okay, name THREE companies . . . I kid!
Actually, I don't think either company quite matches TSR's output in its heydey, but these two would probably come the closest. And the way the both publish their RPGs makes the comparison a bit tricky, IMO.
For Obsidian Path (inheritors of White Wolf's catalog, mostly), they are doing a pretty good job of actively supporting (somewhat) the classic World of Darkness games, the "new" World of Darkness games (or, Chronicles of Darkness), Scarred Lands, and Exalted games (and the Trinity games too maybe?). Is the World of Darkness one RPG line or seven (or more)? For me, the various WoD games are different enough I consider them separate games, even though they share a rules system and story universe.
Obsidian is obviously making very good use of Kickstarter, but to my observation they are (somewhat) developing these many games lines serially, rather than simultaneously. And that's the difference right there.
I used to play a lot of WoD games in my youth in the 90s, but both then and now, I've never felt able to "keep up" with the spate of releases, as awesome as all of the individual games and supplements are.
Fantasy Flight has some amazing games in their back catalog, but to my knowledge they are only actively supporting their Star Wars games right now. Although, it wasn't long ago when it was both Star Wars and Warhammer 40K lines. Like Obsidian Path, is Star Wars one game line or three? Was the recently canceled WH40K games one line or five? Despite the similarities to the White Wolf/Obsidian Path model, I tend to look at both of those game lines as singular games with multiple focuses. But either way, Fantasy Flight has never kicked out books at the same pace as TSR back in the day, I'm fairly certain.
One of the reasons I'm NOT playing the new Star Wars game (maybe not so new at this point) is the feeling that I can't keep up with the three strands of that game and their supplements, I'd consider it if they wrapped them all into one core book . . . The only WH40K game I purchased was the Deathwatch RPG, because I love me some Sphes Mahrines.
Both of these companies however, are certainly putting out more content than WotC is for D&D right now. Is this making these games more profitable? Perhaps, but none of these companies will release sales figures, we may never know.
