>I'm guessing you aren't a gamer.

Followed by calling the game "Fortnight" gave me a bit of a chuckle.

Most people I know just don't buy anything that isn't on Steam. People only use the Epic store cause they give out free games all the time in a sad attempt to get people to use it more, but most people don't care and would rather stay with Steam (while occasionally redeeming some free games on Epic). As for something like GoG, they give you DRM-free portable installers, so obviously some people like that and occasionally use it instead of Steam.
