All I own is Stern.

I would pick Met pro as my first, TWD pro as my second. (I know they are same designer and programmer), if I wanted a slower paced pin with a lot to do instead I'd probably go with Met pro and Tspp.

As for Tron (IM would be as well) are you concerned the code is too brief? Very fun games, but the code is what it is, might you get bored?

Good point, I am just starting to play my Tron more and hardly ever get to SOS. But I don't play it hundreds of times on end. I just figured it would be like once I master Gem shot, it would be like SOS all day long and then Portal. But then I guess if it were too easy, you could adjust the set up and the settings to make it more difficult.

I do like LotR while Valinor may be out of reach DTR is not impossible and feels like an accomplishment when I make it.

IMO TWD pro is rated way too low, I think it should be much higher myself.

I'm still sticking with Met pro and Tspp.

But have been playing Tron a lot for the last 3 days and really can see it being an option. I get one mode from SOS a lot. Sometimes it's Quorra, sometimes it's Gem, sometimes it's Disc. It seems very well balanced at least for me and keeps me hitting start. Have only been to SOS a few times. Today I had Quorra lit and ready started Disc and that would have been it. I ended Disc and drained before I could start Quarra.
