I don't know if Dermmy's and Trunda's contributions to Trainz have been good or bad for Trainz's future. The realism in EK3 using Trunda's greenery is remarkable, and they are about as realistic as is possible - IMO.
I don't see anything coming along in the way of Speed Treez that can be better. The two of them have placed quite a challenge on the creators of trees, shrubs and route design that will stand quite a while as the standard. Once again - IMO.
No one is going to change my mind, and I'm not going to change anyone else's mind. I'm not looking for a pi$$ing contest here. They always turn out the same. Right where they began. Everyone's shoes and socks get soaking wet, and then after the warmth dissipates, the feet get very cold, and no one's mind has been changed.
When Dermmy, or someone like Dermmy, comes along and creates a route as realistic as EK3, without turning my route into a slide show, or having it appear as a bunch of scenes from The Wizard of Oz, I'll jump on board - pun intended. Until then, what I see is not for me.
Moreover, Auran has gotten a bunch of my $$ since I got into Trainz with 2004. In fact I even bought 2010 twice because of a disk crash that destroyed everything, and my backup came back as a mess. So, I'll be sitting out for a while. I see many interesting things coming!
