I don't suffer from FOMO, there are enough games to chose from than available hours on a day, on each platform specific store.
That was a ridiculously hyped launch on Apple's part, considering I had finished the game years before on console...
I'm not missing out on anything if Apple continues to bungle around.
The real question I guess is, why do you need to play a game on three separate boxes?
Who knows what I'll have available next year?
I don't play fresh-from-the-presses multiplayer shooters (moba, survival, battle royale, whatever the term in fashion is this week).
I only (with the exception of Minecraft below) play single player games that don't lose their appeal if they're not in fashion any more, some times years after launch.
So obviously I like to have them available on as many platforms as possible.
And if we're talking Minecraft, I do want it ready on my laptop when I have 10 minutes on the go but I also want it ready on my desktop for when I have actual gaming time.
Humble Bundle? They mostly give out Steam keys. Itch.io maybe. For the indies that are available there.
