First of nice to hear you enjoy NTSP. I designed the reward with 2 things in mind. 1. Failure, it's KSP and not everyone is able to build a stable launchvehicle asap ,) 2. The Prestige Missions. Those are truly expensive, and the next one even more ,). Since you need them to get to the next level of Commercial Missions they are a must have Missions, even if you can neglect them at the beginning. BUT at a certain point with the further exploration of the kerbal system and further raise of rocketcost they are a must have. At the end of Pack 1 there are the first Missions to build rovers. Our Scientists are working extra Hours to advance our Program but you have to remember they are not computers and therefore can't been overclocked to work faster
