Valve is good now so it doesn’t need a competitor? And only when it goes bad should another company exist as competitor? This makes no sense… It’s just not how the world works. Once you have a monopoly it typically stays a monopoly. Look at any of the current monopolies - many are going to shit like Google but there’s no real competition regardless.
You’re also discounting the fact the opposite fact - Epic might be terrible now, but change leadership and its now amazing.
You’re buying way into a very specific case of looking at where things are at now and making a judgement VS. Thinking of longer term ideas like competition is good.
Also, is steam infinitely better than Epic? That’s very debatable, I have no issues with either. To be honest, they’re much of a muchness. You may just be too heavily emotionally invested in these companies. Realistically, they are both just trying to make as much money out of you as they can. For instance, Steams use of their market and giving out digital cards to collect and level up is very predatory.
