Sega's fishing controller is a great (and kind of obscure) piece of hardware :)

In my opinion one of its biggest problems is, that, just like the game it shipped with, is "too much of an arcade game", meaning that you play with it for a short while, but then it looses its novelty and you put it down to play something that keeps you longer engaged.

It's a pity that the Dreamcast wasn't that successful, I mean I would have loved trying to play a game like Dark Souls with with this controller :D
