Post here what you think of the game. Here's my quick-without-revision review I just made. It's not very specific or whatever, but I think you'll get the idea:
Graphics: 4.25/5 The venues and the Rock Den and stuff like that look pretty good. Vibrant in color, and pretty cool. The thing is, the animations are sort of sad... I KNOW that they are LEGO's but I mean, still. That, and the drummer doesn't play along to the beat of any song at all - only the bass pedal does..
Sound: 4/5 LEGO Rock Band has a strange soundtrack. For every good song, there is 1 or 2 songs that suck. For instance, (This is my opinion of course) you've got "Fire", but then you've got "Ride a White Swan" and "Make Me Smile". There's "Ghostbusters", but there's also "Naive" - you can see where I'm going with this. LEGO Rock Band has a lot of GREAT songs and new bands to the Rock Band platform. You can also do an export for $10 on the PS3 and 360, but it should be known that you can't choose which songs you want to keep, and which you want to delete, as the file (1.28 GB, by the way) is just one hunka hunka burnin' HDD space.
Fun: 3.75/5 LEGO Rock Band is a pretty fun experience, but I can't help but think this is really a $50 - or really $60 if you pay for the export - track pack. The story is pretty fun to play through - and the cut scenes and Rock Den stuff is pretty cool. You can also use DLC you bought for Rock Band 1/2 in this game, but it should be known that only songs that past an "E" for Everyone filter will get in. For instance, I have 434 songs downloaded. When I went to make a setlist, it said I had 168. So yeah, while DLC from Rock Band 1/2 will work, not all of it does, as this is a family friendly game. LEGO Rock Band is a decent game that is well worth anybody's time that's a fan of music games... I just think this game will be much more popular for its real target audience - children.
Pros: Some great new bands, cool "new" experience
Cons: Unable to choose which bands you don't want in the export, some terrible unknown bands/songs, not all Rock Band songs work, seems like a 'kiddy track pack'
