Epic cons:

• Filled to the brim with DRM, at the point where you can’t even launch many singleplayer games offline
• Actively against linux, for some fucking reason
• Bad launcher (but this one is no biggie, you can and should use Heroic launcher instead of the official one)
• Bad store in general compared to steam
• Ties with Tencent (super anti-consumer chinese state-owned megacorp)

Epic pros:

• Free games
• With coupons prices can get VERY low
• When it opened I heard the percent they take from game devs was lower than the other stores (not sure if it’s still the case and tbh if it ever was)

Steam pros:

• Pushing linux gaming like their life depends on it
• Generally correct towards the consumer
• Huge store and many information, from the game store pages to the workshop
• During sales prices are good

Steam cons:

• Drm
• Bad official app Ux and messy ui

Gog

I don’t know anything besides the fact that it has drm-free games and that it’s owned by CDPR (the guys who developed the witcher series and cyberpunk)

I personally purchase my games on steam, since I think their contribution to linux gaming is crucial for linux to go mainstream
