I've finished my work on these two scenarios. They will be released with Star Trek version 1.0, but I only started making them after I finished the Xindi scenario so the fact that I got them finished so fast is a good sign. For the 22nd Century scenario, exploration is a key part as you start with only a little bit of the map known (unless you're the Vulcans) and few diplomatic contacts. Fort the Romulan War scenario you start knowing the map and can play as either one of the coalition words or the Romulans. Both scenarios include a tech tree (the same tech tree, as they are based on the same mod).
