Far from it. New songs unless someone got lazy and began to recycle. Add-ons from III can carry on to WT. Best Guitar Hero ever: Warriors of Rock or Metallica.
Guitar Hero World Tour has BYOB on it. That's it though.
No
No you can't. And you can't import RB1 songs to RB2, like on other systems.
It depends if the Guitar Hero 3 songs were released as DLC on GH: World Tour. There is no way to directly import songs from Guitar Hero 3 onto World Tour.
yes. only if it is for the same console
No it only includes 1 guitar but unless you have a 2nd guitar you can use that(only if it was for the other guitar hero games)
NO
no
I am not sure but I know you can create songs on guitar hero world tour. I was searching for the same question. I also know that you can download songs already made at the playstation store. (playstation store/addons/disc based games/guitar hero 3)
You can add your own custom songs to Guitar Hero World Tour. You cannot create custom songs through the game however.
No, Guitar Hero 3 has no DLC, if you wanted to put new songs on it you'd have to hack it somehow. The new Guitar Hero: World Tour will have DLC though, you'll be able to download songs onto and play songs from your SD cards (they will probably let you download all the songs from the previous games).
