I could see them putting the base sub on gamepass but make you buy the xpacs. So basically classic on gamepass.
This varies a lot.
IF the sign-up process changes, and having Game Pass becomes mandatory… then yes, 5 PROBABLE million players would have access to Game Pass if they wanted to play WoW.
If it’s a mix… probably some players would prefer to stay on Battle.net and others, via Game Pass for specific advantages.
What I believe matters is:
On Game Pass, I believe new players would come to WoW.
The idea is: how many millions of players have Game Pass and would play WoW to try it out?
And if they like it, it could make these players keep either Game Pass or the WoW subscription.
Now… would this bring in NEW players and maintain it ? I’m not sure about that…
I know that, based on examples from close friends:
Not everyone continuously pays for Game Pass because they play something, then stop, and don’t renew Game Pass until they want to play something again.
With WoW, maybe that could change, and there are friends who don’t pay for the WoW subscription because they find it abusive to pay monthly to play just one game.
