I never understood that. I figured it's just the general 'they changed it so I hate it' reaction of peeps who don't wanna move to another distribution platform. Anything to add some competition to the market and get valve to make some long-needed changes to Steam is good in my eyes, even if it is a little inconvenient. Honestly, the biggest problem I had was every publisher and their mother making a brand new distribution platform for like, six games. Here's looking at you, origin.
Anyway, this game looks like cash fucking money. I'll buy it once the price goes down a tad, seeing as how I'll be picking up WOTC soon since I waited for the same from it.
Having to use many different programs is detrimental for the consumer, both because of the inconvenience (remember that the main benefit of Steam initially is that unlike other methods of buying games, it is was more convenient than piracy) and because the more small launchers there are, the greater the chance one you're using will go under and take your games with it. Remember the shenanigans with Impulse, the old Steam-killer? Or what about Desura, slightly more recently? It's not at all unreasonable to place limited faith in the longevity of the current batch of challengers. Furthermore, there's the ethical issue. Desura and Impulse both stood on pretty solid footing in this regard, before they were bought out, and that change hastened both of their demises even if mismanagement was a bigger factor in Desura's case. As a final nail in the coffin, these things typically have a terrible user experience, and Epic is no exception. Personally, I just recently opened the program and found that they got hacked and blocked my password. That's what they should do if they get hacked, but... Steam doesn't really get hacked. And it took me a bunch of tries to reset my password because I needed a new password email for each of the shitty errors they threw. And even when it worked, that wasn't victory, because I didn't know it worked – the password reset threw an error then too.
On the plus side, after I got into it, it gave me Slime Rancher for free. In fact, it seems they give a free game every two weeks. Which is cool except... I could have got it for free easier by pirating. Getting free shit on the internet isn't hard. People like Steam because it's better than free.
As for this game, for me, this has shunted it into the same category as Six Ages: looks good, but I won't be playing it on anything like launch even though I would if I conveniently could.
