Last weekend something very special happened, that will probably be quite appealing to hardcore gamers and newbies alike. A new game Guitar Hero: Aerosmith was launched, which allows players to rock out on the music of the legendary band alone.

Activision is definitely on a roll. At the end of May, the company has set the price of $189 for the Guitar Hero World Tour, with all the instruments included. This is $10 more than Rock Band’s PS2 version. So far, the tracks that have been confirmed already include Van Halen, Linkin Park, The Eagles and Sublime.

Guitar Hero World Tour will be released sometime after the summer and will feature wireless instruments (drums, bass guitar, and microphone) and a music studio where users can create original songs (no vocals included unfortunately). It will also come with an online mode called Battle of the Bands, where the members of two bands can engage in a musical competition to see who has a better grasp on instrument handling.

In the last week of June, according to The Financial Times, Beatles representatives have received visits from both Activision and MTV Games (maker of Rock Band) people. It seems the two companies are looking for a way to bring the history-making band aboard, in what was said to be a deal that "could be worth millions of dollars."

Activision is expected to soon launch another special edition of the Guitar Hero game featuring Metallica.
