I reccomend buying Guitar Hero III, and incase you don't know what it entails, I'll tell you, because its different from other games....;
Guitar Hero III doesn't use a Wiimote, well, ....not exactly.
Guitar Hero III has a Gibson Les Paul styled guitar controller, with 5 fret buttons, a strummer, and a whammy bar. You put the Wiimote inside the guitar for battery life, and to trigger Star Power, by tilting the guitar controller. (tilting is optional, you can press the - button on the guitar controller, if desired) Star Power is a system in the Guitar Hero series, and when it's activated, it multiplies your score up to 8 times as much, it can still be 4 times as much without Star Power activated. The music in the game is from real bands like Guns 'n' Roses, Foghat, ZZ Top, and more, and has more than 70 music tracks.
So thats one of my reccomendations, and i have more, do you wanna hear 'em? Im always happy to help. And by the way ......Welcome to WiiChat, I hope you enjoy your stay.
