I like two things in particular, @ilan:
Yay, another Kerbal Space Program player! I love that game, I can easily lose days playing it. Now, I just need to make my heavy lifter a bit stronger (It can lift about 80 tons into orbit with 12000 dV remaining, I want it to take at least 120 tons into orbit with 16000 dV remaining. Do I need to tell you that my launches play like a slow slideshow?).
