It really depends on how popular the anime gets. If it works, the games will be popular, if not, they're going to flop veeerrrry hard.
It might just be me growing up or something but the Anime didn't really catch my interest. I watched some subbed episodes but I just couldn't get into it. Like I said, maybe kids will love it. I hope the Anime does well enough to capture consumer interest or like you said, it'll flop like a Magikarp.
