Given the soft response for the anime tinged Let's Fish: Hooked On, perhaps there's more of a market for a more chilled fishing title. That's what Natsume must be hoping for, as they announce Reel Fishing Masters Challenge for the Vita, out this year.
A pure fishing simulation experience, it offers 18 fishing
locations, 60 fresh and saltwater fish, and over 100 bits of tackle to fiddle with. Here's some screens, apparently there's an interesting story to go along with the game, but I'll be quite happy with a worm on a rod by a nice patch of lake.
