We've already had one new take on Breakout in the form of Shatter, but the block-smashing formula can be made into more of a puzzle instead, as demonstrated by DSiWare title Reflect Missile.

Rather than a paddle and ball, you've a launchpad and rockets, and while they can bounce too, you won't really be playing this game with that aspect in mind.

The Tower Defense genre has always been a home for small projects as well as large ones. It started with Flash games for your browser, and the gameplay is something that doesn't take much effort to get used to at all.

As such, it's an ideal genre for a downloadable Nintendo DSiWare title by the name of Starship Patrol, or your regional equivalent - and perhaps more obviously relating to its genre, Starship Defense.

You've got a starship to defend, and turrets to defend it with. You know the rest.
