what’s the issue with Epic

Enshittification.

why should I go for Steam

Not sure you should.

or GoG?

I hear GoG tends to be less DRM-y.

As for minor issues, EGS does not have feature parity with Steam or GOG. They don't have user reviews, for example. This makes it a worse user experience.

More importantly, Epic has a habit of anti-competitive or anti-consumer behavior. When EGS first launched, they were keen on doing console-style timed exclusives, even for games that were already purchasable on platforms like Steam.

Lastly, Epic has a history of neglecting or shutting down games. A few of their older games were taken offline permanently when Fortnite started gaining traction. They then purchased a few studios, namely Psyonix (makers of Rocket League), Mediatonic (Fall Guys), and Harmonix (Rock Band/Guitar Hero series). These studios seem to be a shell of what they used to be. Psyonix's first major project under Epic was Rocket Racing in Fortnite, and this project seemed to be prioritized over Rocket League and even caused the removal of core features of Rocket League. Harmonix worked on Fortnite Festival, but that came at the cost of Fuser, which shut down and was delisted about a year after launch. As for Mediatonic, I don't think they worked on anything else yet, but a large portion of the studio was recently laid off. Needless to say, fans of the affected studios aren't happy with Epic as they're being treated as 2nd-class citizens compared to Fortnite players.

Epic’s customer service sucks. Consider my last experience from a prior xmas sale:

• had multiple games in the cart with discounts applied, checked out with paypal, but for whatever reason the communication broke and didn’t go through
• my cart then got stuck in a limbo where I couldn’t check out with any method to receive the discounts, everything was full price again
• opened a customer support ticket to get the problem resolved, then went through 3 days of back and forth, explaining the situation over and over because
  • each of your replies are handled by whoever the next agent is
  • who apparently don’t read any history of the ticket, so they provide feedback or advice that already didn’t work
  • and it can take a full 24 hours or more to get a reply that ignores all previous replies
• by the time the error was resolved by a competent person, the sale was over by only a few hours
• despite the fact that I only missed the sale window because their reps were incompetent, they refused to make any exceptions to apply the sale prices I had been trying to checkout for 3 days

So, fuck them. I only claim free games from them now.

And I concur with problems other people have mentioned.

They're partially owned by Tencent, a big Chinese company. And as Chinese companies are, the government has direct influence over them. And while Tencent is not a majority owner, Tim Sweeney happily took Chinese money and now pays his co-owner a portion of the profits which then go to pay for Chinese gulags.

There are many things, especially hardware, where it's impossible to avoid Chinese companies but simply buying games somewhere else is super easy. It's obviously not a perfect system because even on GOG there are games using UE, but just buying games somewhere else is such a low barrier, it's not an inconvenience at all.

That said, claiming the free games doesn't help them. It helps the developers making those games because Epic has to pay them and won't get anything in return if that doesn't result in users leaving money in EGS for other things.

The first major issue for me was that the launcher was a crypto miner and they didn't tell anyone.

Since then, I have 0 trust in them and refuse to install the launcher. I don't care for the "free games"

There's not really a good answer other than convenience. Folks view Steam as the benevolent convenient monopoly. They want it to be their store for everything, their launcher for everything, their friends and social networks for all gaming on PC and what not. Epic is behind on feature parity and function, but even if it did have parity, I think gamers still want the convenience of one store/library/friends list.

Pure speculation: of the people who don't like Epic, maybe 25% are legitimate, principled objections to their business practices. The rest are split evenly between people who just want to manage their entire library on a single platform, and folks just going along for the hate-ride because it seems like the "safe" position to take.

From a technical stance, Steam and GOG are superior platforms (for different reasons). For equal-price purchases, I can't think of a single reason to choose Epic over other options. But claiming a game for free? That doesn't make anyone a bad person.

Steam and GOG are simply better platforms overall. If you really care about being DRM free and owning your games you go GOG route, otherwise Steam is the king. Epic does not even have a review system.

Epic however is the best source of free games on PC. A lot of the latest games I have played have been from Epic giveaways. Right now they have Outer Worlds and yesterday it was Ghostwire: Tokyo, both of these games I played few months ago after purchasing them through Humble Bundle.

Will I ever buy a game on Epic? Probably not, I prefer Steam, but those that simply refuse to redeem freebies and install their launcher while shouting things like it being spyware are weird.
