Quoted from Shapeshifter:Tron is starting to feel dated.
The game's popularity was partially due to the pinball scene at the time. There really weren't many good newer games back in 2010. The hot games were still 90's DMD and maybe LOTR or TSPP. Times have changed, and I don't think Tron holds up to some of the new releases from the last few years.
I'd like to see a Torn VE, but I don't think it would be as hot of a title as Pinside makes it out to be.
