Euuh depends on the price. I'll mention some less known or new ones.

Wii
Geometry Wars Galaxies - €5 - One of the most fun Wii games. Too bad it's disc-based instead of downloadable.
Link's Crossbow Training - €10 - Great arcade shooter in the style of Wii Play. But in the Zelda world, with about 30 levels.
Battalion Wars 2 - €15 - Fun squad-based shooter. Mix of shooter and strategy, in a cartoony style.
Fire Emblem: Radiant Dawn - €15 - A great Fire Emblem game. Must-have if you like the series.
