Epic explains why it hasn't sued Nintendo, Sony and Microsoft over 30% fee | Epic vs Google

The lawsuit vs Google should have finished in the first 5 minutes:

Epic: Google charges very expensive to use their services

Google: we allow to side-load apps, you're not forced to use our store or our services.

Fortnite firm says platform holders' hardware losses justify the need to charge devs for game sales and microtransactions

So, in other words, he's not suing them because they're not as profitable?

I feel like this really isn't going well for Epic.

Alternate explanation: they want to side load their store, and that's way easier on a phone/tablet vs a console. Follow the money, suing Google and Apple is way more likely to be profitable than suing Microsoft, Sony, and Nintendo.
