I get free games every month with Amazon Prime. I can only use this via the Twitch launcher (doesn't even work on Linux AFAIK).

Borderlands 3 I bought when it came out on Steam, I believe in start of Steam release it was on sale. Else I wouldn't have picked it up, simple as that. They release DLCs for the game, so that's nice, and keeps it a little bit alive I suppose.

Guild Wars 2 recently launched on Steam (like 8 years after release). I cannot merge my Guild Wars 2 account to Steam though, so its useless to me.

Humblebundle, in contrast to platforms like EGS, yields you serials you can apply to a launcher, usually Steam. That's convenient, but I suppose it isn't for people who don't want to use Steam.

Though I'm a heavy Steam user, so Steam being the defacto standard is fine with me.

I don't want another launcher, therefore I either use Steam or use Lutris to abstract all other launchers (and emulators and such).
