Personally I wouldn't, but I grew up in the 80's, and the three (3) original IJ movies were a huge part of those formative years for me, so I absolutely love the theme. I love the art too, so it looks good just sitting there when I'm not playing it. I also love the game play, so it's a 3 times win for me with theme, art, and gameplay. Now I know that's just me, and everyone does not feel the same way.
Tron.. I love that too, LOL. For all the same reasons as the IJ. The Tron movie and video games of the 80's, the art is good to great, and the gameplay is excellent. I would love to have one, but I can't part with my IJ for it. I do look forward to getting a Tron down the line some day, the hard way (by buying it outright).
