There are two sizes of Tron figures that would work for the Tron – Disc grid game. Both the poseable 4” figures as well as the 3” figures would work. You could conceivably use the 6” or even the 12” figures for added realism, but you would need a lot more space. The rules will scale upwards without too much trouble.
While the 3” figure sets never made their way up here I did get one through the mail in a pack with a light cycle. The figures (and cycles) in these packs come on 2” hexes. I did pick up a bunch of the 4” figures at Dollarama when they appeared for $2 each. Now that I want more I can’t find them anywhere. Although after checking 4 stores I was finally able to find two more Clu Sentries that I can repaint for the Grid. These 4” figures also come with a stand that is 2” in diameter.
Since I plan on making zone-of-control discs to put under the figures, the same ones will work for both the 3” and 4” figures. You could even use counters if you wanted to. I suppose I could always make a 2” counter to replace the figure if needed – like the pogs in Heroclix or Crimson Skies. But, since any figure that would fit on the disc could be used, you can use Star Wars figures, superheroes, or even the small GI Joes.
While I could use the discs that come with the 4” figures for the game discs, I will probably end up making some out of either layered styrene or even cardboard. If I was more proficient with molding I could make a gang mold of them and cast up discs to use.
