I'll say a few words about the add-on. For me, the only significant plus of the WT version is the simultaneous turn capability. Since it works great, a whole lot of priceless time is saved.

Captain happened to have some very distant connections here with programmers who could have helped me a own same in development... but alas, I haven't been able to contact them yet.

The other changes regarding gameplay are more of a minus compared to SoD. Also, the messages about terrain type during another player's turn are annoying; it would be good to remove that nuisance.

1. Now terrain type messages appear much less frequently - only if there is another terrain type nearby (a closed cell is also considered another terrain type)
2. I think this feature should also work on another player's turn... after all, you need to plan your move and it's better to do that with information about the land.
