While we were certainly high on the fab four's foray into the world of Rock Band, it seems the rest of the world may have taken a slightly more nonchalant approach to the game. Despite selling over a million copies - more than Guitar Hero 5 managed, which was released in the same time frame, the game's performance was considered disappointing by its publishers, EA - especially when they'd done such a good job putting the together.
Of course, when you take into account the fact that EA had allegedly had to pay the Beatles and their estates between $10m and $40m, for the rights to use their songs and likenesses in the game, you begin to understand why phenomenal sales would be needed in order for them to make anything approaching their money back.
Luckily for EA, however, they're feeling a lot more upbeat about the upcoming Green Day: Rock Band - mostly thanks to the band's younger fanbase. In an interview with trade magazine MCV, MTV Games head honcho Scott Guthrie said that the company were "pleased with the performance of Beatles: Rock Band, but we were expecting higher sales."
"Our core audience of 16 to 34-year-old males are much more familiar with Green Day music than The Beatles."
Of course, while we'd argue that the Rock Band series' core audience is probably closer to a 50:50 split of male and female, and is enjoyed by people of all ages, we can also see his point. Some of the Beatle's more mature fans may have either not known about The Beatles: Rock Band, or may simply not have owned a Wii, or 360.
Either way, EA and MTV don't have too long to wait to see how well their game performs, as Green Day: Rock Band hits these shores on the 8th of June.
