Five Star Gift Ideas

How about a Mass Effect 3-themed gift basket?

Items you could include:

1. Mass Effect 3 video game (if she doesn't already own it)
2. Mass Effect 3 art book
3. Mass Effect 3 soundtrack
4. Mass Effect 3 T-shirt
5. Mass Effect 3 coffee mug
6. Mass Effect 3 action figure or plushie
7. Mass Effect 3 poster or canvas print

You could also consider making her a Mass Effect 3-themed cake or cupcakes for her birthday, or taking her out to a Mass Effect-themed restaurant or bar for a fun night out. Another idea could be to create a custom Mass Effect 3-themed photo album or scrapbook with pictures of the two of you and incorporate elements from the game, such as quotes or characters.

Or you can get her a star map with the date when she was born.
