LEGO Rock Band (DS)
vs
Rhythm Heaven (DS)

Lego Rock Band is a music video game and part of the Rock Band series developed by Harmonix Music Systems, but also incorporates elements from other Lego video games as developed by Traveller's Tales. The game, as with other games in the Rock Band series, will allow up to four players to use instrument controllers to play lead and bass guitar, drums, and vocals on a number of rock music songs. In addition, aspects of building with Lego bricks are incorporated into the game, allowing players to customize their avatars and other band assistances, and include additional Lego-themed gameplay modes.

Rhythm Heaven, known in Europe as Rhythm Paradise and in Japan as Rhythm Tengoku Gold (リズム天国ゴールド Rizumu Tengoku Gōrudo?, lit. "Rhythm Heaven Gold" or "Rhythm Paradise Gold") is a rhythm video game for the Nintendo DS handheld video game console. It is the sequel to the Japan-only Game Boy Advance title Rhythm Tengoku. Rhythm Heaven was released in North America on 5 April 2009, along with the release of the 3rd generation Nintendo DS system, Nintendo DSi. Rhythm Heaven has the player tap, flick, and hold the stylus on the touch screen to make a beat to match the background music for the level. The Nintendo DS is held on its side like a book with the top screen on the left and the touch screen on the right (vice versa in left-handed mode).
