And the price should reflect the game's current state/value, not some hypothetical roadmap.

So more like Kerbal Space Program, less like Kerbal Space Program 2.

Exactly this. I tell my friends not to get their hopes up too high about Palworlds eventually being completed because the studio has a history of abandoning titles in early access. I'm not telling them not to buy it or that it's not worth purchasing, but to weigh if where it's currently at is worth the price they're charging.

The studio may use the funding they got from its spike in popularity to actually complete a title just as well as they might sell out to a bigger studio (I'd imagine The Pokemon Company would love to buy then bury it), or abandon it entirely. We don't know what the future holds and we do know the studio has a history, so keep that in mind when you're purchasing or when you're asking yourself if it was worth the buy.
