Here are a couple of ideas I have as I am playing this game: 1. What about adding some city graphics to make Kerbal look more alive? 2. What about adding weather to Kerbal for a little more realism? I live near NASA and there are times when flights ares scrubbed due to weather etc. 3. Adding paint and decals to the rockets? 4. Promotions for the Kerbal pilots? Once your hire them they would gain credentials and rank as they do missions and return safely. This would put a little more at stake if you send a seasoned pilot on a dangerous mission and could possibly loose him.
