The number of members isn't as instructive as the number of man hours that went into the development of the product. Plants Vs. Zombies (an 'amazing' indie game) apparently took 12 man years of development (and probably at > 40 hr / weeks). That's a lot more effort than most albums, that's for sure. Even if a band takes a few years to put an album together, there's not spending 40/hrs a week in the recording studio for two years. AAA games have hundreds of man years of development. When you start talking about long, uninterrupted development cycles, it's very difficult to do that without external funding. A small band can go on tour and play gigs while working on their album - or even have a day job to pay the bills. If you have a day job while working on a game, you're not going to finish (anything non-trivial).
