For a relatively new service, today's DSi update is pretty light, with just one new game now available for download. However, on the plus side, it is actually a game, and not some clock or calculator. In fact, as promised during E3 last week, it is Mario vs. Donkey Kong: Minis March Again! The third game in the popular Mario vs. Donkey Kong series – which started on the Game Boy Advance in 2004, and continued in 2006 on the Nintendo DS – Minis March Again has players controlling the titular toys once more, this time trying to rescue Pauline from the party-crashing clutches of Donkey Kong in a new theme park. Apart from once more testing the digital distribution waters (this is a fairly major release, and it is going to be download-only), Minis March Again is also another milestone, being the first time a game with a level editor has been made available of the DSiWare service. Minis March Again can be downloaded for 800 DSi Points. The official description can be found below:
