Epic has spent the last few years campaigning to sway public opinion of Steam. Their whole campaign relies on making Steam seem like a monopolistic cesspool of shovelware and garbage, and they need to present themselves as having the moral high ground to do that. Never mind that NFTs are more predatory than at-your-own-discretion purchasable pornography.
And once again it shows, if you wanna surpass a company you don't do it by attacking them, but by providing superior service or product.
Now let's look at why they are failing: Epic Games got some good original games. BUT: they are trying to buy exclusive licenses to force players to use their client, and they didn't even make sure their client makes for an ok experience. The menus feel sluggish and blank (except for the store which is ok at best and very inconvenient to browse), the ratio of clicks per functions is very bad, the function range is very lacking and things haven't changed over the last 4 years.
Let's acknowledge that in addition there's quite a few bugs still roaming around. For example: for about a year now I am unable to open the friends list in any way shape or form.
"That said, the AO rating assignments were not a direct result of them being blockchain games, but rather how that was implemented.
"As is the case with all games, age rating assignments are dependent on the content of a game and the context in which it is presented to the player. The ESRB age and content rating system assesses whether products may reward real money, prizes with real world value, or something that can be exchanged for or converted to real money (i.e., gift cards, cryptocurrency, etc.), as well as whether there is cash spent to be eligible for such rewards. While it is not a blanket rule, it is possible that a blockchain-enabled game or app will warrant an Adults Only rating category assignment due to a combination of the factors discussed above."
So I guess this probably covers most if not all "blockchain games" but it's technically only the ones that are real money gambling.
