Why are there both PC and Mac licenses?

[Penthea]

I guess I just have a sour taste with this because the game is not designed for MacOS much less M1 Macs; conversely if someone looks at WoW not only is the game now native for M1 processors but you only need one copy of the game and no multiple copies of multiple expansions. They both have monthly fees and in-store cosmetics but for WoW the players only need one copy, one sub, one account, and can play on multiple platforms.

I completely get that and I would feel badly about it too if I were in your position. However WoW expansions cost more than FF expansions, which basically means they're essentially doing the discount that I mentioned SE should do in my previous post. FF expansions are cheaper but only cover one client. WoW expansions cost more but cover multiple clients.
