I buy all my games on Epic Games Launcher becomes it has less DRM than steam. If you have kids, they can't play 2 completely different games on two different computers.
It's like your kid not being able to play Mario kart on her switch because her brother is playing Halo on Xbox in another room. Steam doesn't support that. Epic games doesn't have a problem with you having 2 different games being played on 2 different computers, so I buy my games there whenever I have the choice because it's the more consumer-friendly platform.
