No it won’t - people are lazy

Even CDProjekt sold many more copies on steam than GOG when you

1. Actually own the ge there instead of renting a licence for it.
2. Know that 100% of your money go to the game developers.
3. Get many additional goodies for free

Don’t tell me people are choosing the better deal when it’s all just steam having the might of “I have most of my games there already” on their side…
