Our new Indie Games subforum is now open for business in G&T. Go and check it out, you might land a code for a free game. If you're developing an indie game and want to post about it, follow these directions. If you don't, he'll break your legs! Hahaha! Seriously though.
Our rules have been updated and given their own forum. Go and look at them! They are nice, and there may be new ones that you didn't know about! Hooray for rules! Hooray for The System! Hooray for Conforming!
I thought it was weird that Tycho thinks that the GH guitar, with its five buttons, could make a serviceable instrument. Problem is, you have 13 notes in an octave, and I assume you wouldn't be using hammer-ons and pull-offs to make different notes on the scale, as that would be grossly counter-intuitive. 5 buttons for 13 notes just isn't going to work. Using button combos for different notes (which would give you just over two octaves--a 24-fret guitar has has four) would be extremely unwieldy.
5 buttons with hammer-ons, pull-offs, and both down and up-picking might sound like a lot of combinations (you could model that as 7 states per button including the off state, and that gives you 2401 states), but when you consider that a real electric guitar has as many as 120 fret positions with even more possibilities per fret when you include bends, barre chords, finger and sweep picking, palm muting, and so on, a real instrument offers many orders of magnitude more possibilities.
I'm not one of those snobs who thinks people who play GH should take guitar lessons any more than people who play Burnout should drive race cars. Just don't kid yourself that playing Guitar Hero is any closer to the real thing than Burnout is.
