This week the XBLA gets two full games and there's not a single crappy arcade port to be seen. The first release is Space Giraffe, a shooter that may or may not take place in space but doesn't seem to have any giraffes:

Space Giraffe features uniquely beautiful graphics and 100 levels of lovingly hand-crafted shoot-em-up action gameplay from the makers of Llamatron and Tempest 2000. Collect power-ups to activate Bonus Rounds and master the strategies necessary to maximize your score on every level!

* Extensive gameplay: Play through 100 levels of shooting and strategy.
* Level design: Enjoy the unique graphical appearance of each level due to the use of the Neon engine.
* Special features: Learn special moves to increase the Bonus multiplier, and collect power-ups to gain access to the Bonus Round.
* Bonus challenges: Finish all 100 levels to unlock a hidden gameplay mode.

This week's other release is Street Trace: NYC, a sort of boring-looking hoverboard racer. But hey, what do I know? Maybe hoverboard racing games are making a comeback.
