As the scenario author, I have to agree that the conversion is graphically perfect! Well done, and thanks. (Is it Fairline who did the unit graphics?) I have been playing through it the last couple of evenings. One thing that doesn't work the way it should is the stackable squares: the idea with STC (as an SP game) was to make it hard for the player to besiege AI cities. If you can stack your units, it's just too easy. Can that feature be turned off easily?
I'm glad you like the ToT conversion. Yes, the units are made by Fairline, his visual quality is incredible. For the issue of more than one unit being removed, it is well explained by Tootall. That exceeds the conversion, and it is because I do not like to lose several units in a single attack, which forced me as a player to always carry a Settlers unit, accumulating the transformation, to generate a defense in the attack zone . This is how to play with ToT, but with ToTPP, I modified that option and some others in @COSMIC2. I decided not to delete it in the versions after ToTPP, because I thought it could be used or discarded by the players. But certainly I never thought that I could modify the structure of the game for "new" ToT players, who already started with the PP. In this case there is no problem in the downloads, because it is from Catfish, but in the conversions of your scenarios made by me, I have no problem removing that addition. You tell me.
