I don’t want to be a steam shill, but does the prevention of selling games cheaper (if this is true or effectively enforced) even do any good? I have over a thousand games on Steam, but I doubt I bout 10% of the games from them. Heck, the latest game I remember buying at release was Oblivion Remaster, and I got it from GMG because it was 17% cheaper on release day then on steam. This happens constantly.
If we are to objectively look at the problem, why would lifting this rule automatically mean games would be cheaper elsewhere? One of the biggest slogans in favor of Brexit was something along the lines: “of EU membership costing 350m pounds per week, lets spend it on the NHS instead”.
