Especially if you're only a fan of the original Star Wars trilogy. I'm currently playing Knights of the Old Republic for the first time (yay getting on board with a 2004 game!) that was $20 at the Mac app store. This is T3-M4 the R2-D2 equivalent from 4000 years prior to the original trilogy. It doesn't have the same charm as R2 but does look like a faithful dog of sorts. I am sucked in for over 10 hours of playing so far and not even a 1/4 of the way in, so there went my weekend and here came a screen shot.
