But enough of the rant about the guitars. But it's a shame as if you two guitars from different systems they sadly wont work. perhaps there's a deep rooted difference in the control inputs that is impossible to overcome. However from an engineering perspective why Activision didn't develop a guitar that worked with both consoles (Even if it does use a USB dongle, because the Wii does have 2 USB ports that are often overlooked) I don't know. It's a lovely touch that is sadly missing from the PS3 version.
Now both guitars are the same in appearance except the Wii's is white and the PS3's is Black (Standard livery colours for the consoles), but because the Wii's used the Wiimote it has rumble and speaker capabilities, which actually is really good, as bum notes sound through the Wiimote (Brilliant on 2 player modes) and when "Star Power" is achieved the guitar gives a little shake. The PS3 version uses a (Quite frankly shit looking) USB dongle to receive the signal from the guitar. the Wii version used the Wiimote inside the guitar and transmits back to the Wii. mash the coloured buttons in time to the music. Now in essence the two games are identical.
So when I got back to Kent we cracked out my version.
I played it and absolutely loved it (Even tho I sucked at it). For Christmas I got a copy of Guitar Hero 3 for the PS3, but before I got a chance to play it me and Nomi went around to her friend Lucy's house where she had a copy of Guitar Hero 3 for the Wii.
