Hello, I just downloaded the demo version last night and spent 4 hours (until 3:00 AM) figuring it out. Basically my experience went: 1. Build rocket 2. Push a lot of buttons trying to get it to go 3. Finally hit spacebar but the stages aren't set up right so you just separate the command module 4. Do this several times until you get the stages figured out 5. Launch rocket - it crashes and burns due to lack of control 6. Re-launch rocket - it crashes and burns due to lack of control 7. Discover SDS 8. Re-launch rocket - it crashes and burns because I forgot to turn the SDS on before launch. 9. Re-launch rocket - it fails because I jettisoned my liquid motor with the SRB's 10. Play with stages to get SRB's to jettison 11. Put on too much extra junk, still can't reach orbit 12. Scale WAY back but release SRB's too soon and rocket fails 13. Finally launch right but only sub-orbital flight achieved 14. Launched right and heading 135 degrees, only sub-orbital but for a longer distance!!! 15. Re-launch, get everything right and HOOORAY! ORBIT!!!!! Now, my plan is to grow this similar to a country's space program. Step through meeting up with another space craft, docking with that space craft, using that to build a rocket to go to Mun. Is there a good scenario/challenge to walk through this or just the good old trial and error?
