you could try answering, but conceding works just as well

and why would gamers not buy their game elsewhere?

sounds like YOU don’t know what a monopoly is

if it’s not justifiable, then the game devs can go elsewere.

that seems like an issue that the makers of games can decide. they are not under any gun to choose steam. if the devs don’t see value in steam then they can go elsewhere. for me as a buyer it’s steam, or it’s the developers own website. i will not buy from another store front
