There have been 4 paid DLCs, Castlevania is just the latest.
However, I agree it’s been all worth it until now. Every new area feels like a new experience with cool new gimmicks, gameplay has been refined with stuff like the backpack, we got cool free indie crossover stuff…
And Return to Castlevania has more love for the series in it than anything Konami has done in the last 15 years (which is not saying much, fuck Konami).
I’m okay with the next DLC being the last. The game has had a fantastic life, and I wouldn’t want it to go past the creators’ motivation and start becoming bland. Excited to see what Motion Twin and Evil Empire have in store now (though Motion Twin’s situation seems a bit complex).
