Now this is what’s actually important. No one should care that Nintendo’s IP was “stolen” when they “stole” the IP from DQ first. However the possibility of Palworld being abandoned in the future like Craftopia is a possibility. Part of the reason I’ll be waiting out for the 1.0 release before purchasing.
With Early Access titles you should only invest when you are happy with the current state of the product even if it was not developed further. If you are not, do not buy.
