Everyone loves Star Wars. If you don't love Star Wars, you're wrong.
Some people love Star Wars so much, they want more things to be Star Wars. Forevergeek.com has taken 50 Star Wars Mashups from all over the internet and thoughtfully put them all in one place. Here are the video game tie-ins from their site (and a bonus one that I found.
Angry Birds: There are plenty of Angry Birds/Star Wars mashups. Bite.ca created a line of t-shirts based on the idea, and The Official Star Wars Blog has screen shots of what this unfortunately-still-totally-made-up version of the game would look like.
Assassin's Creed: As the deviantartist who created this mashup says, "It's Ezio Auditore da Fire... da... Coruscant? XD It's Ezio as a Jedi!" The artist has since created a Sith version of the image, and posted it to his gallery.
Mass Effect: Here's another Deviantart gem, Shepard vs. Boba Fett. Who would win?
Super Mario Bros.: The last Star Wars mashup doesn't focus on one game, but tries to mash together these two complete universes. Someone out there took it upon themselves to create a series of these paintings. Awesome, or kind of creepy?
BONUS ROUND—Zelda: Forevergeek missed this awesome Zelda/Star Wars mash-up, and I couldn't resist including it.
