Hmm... interesting scenario you got there. What would that be like, the Klonoa remaster on the Switch? Well realistically, it seems nearly impossible. But if it were possible, I'd say it would take as many sales as it would for any other series to warrant a sequel. And how much is that exactly? Well... I have no idea. I just know that they'd need enough sales to get a profit.
Oh, the day when Klonoa 2 gets a triple A remaster for the PS4 with orchestrated music and a hard mode; I long for thee.
