Why just fish? Imagine catching those damned dragonflies with the revmote as a netm or how cool would it be to have precision drawing to create your own patterns instead of using the original grid.
Why stop there? Chopping down trees would be cool too. Or...
What if you can pick up a guitar and jam along with K.K. Slider in a cool mini game where ya strum the 'strings' with the revmote while using some of its buttons, as well as maybe the z1, z2 triggers, or the control stick itself, kinda like using the ocarina of time or the windwake in their respective games. i can picture it now. like a weird hybrid of that style gameplay with a donkey konga-rythme style, where you hit a button on screen to produce a note while struming a certain tempo with the revmote. hmm if that were the case I'd say using the buttons on revmote would be akward, but im sure if using the nunchuk attachment simply pressing in one of the four main directions would be enough notes, you only need four chords at most for K.K.s songs, and pressing the z triggers could create a different tone or key. man i hope somewhere out there one of their developers is reading this.
on top of that, using the revolutions virtual console, i can see them implementing a way of bringing back the NES games within animal crossing. i know they will most likely charge to d/l those games, but imagine if they did something where either you can compete against other people in your community, or even have your town versus another town (assuming four different players via wifi were living in the same town) in a sort of feild day where the prize from nintendo itself is a free NES game. maybe even having a way to purchase an NES or SNES from a traveling salesmen, which then lets you play any games you have saved either on memory cards or internal memory. genious!!!
If thats the case, i wonder if you would be able to buy an nes or snes seperately, i'll just assume n64 games would a lil too much to ask for, OR...just let you purchse a revolution in the game and let you use it's virtual console. makes ya think doesnt it?
