it's a great game and really addictive, also it's not easy to get through. my dad and I started playing this week, and though my dad's been playing longer. the reason would be because he can't fly worth beans. the rockets are amazing the fact it actually makes you either complete missions or spend obscene amounts of money you don't have to buy them off provides a challenge to upgrade your rocket. the main problems i've been having are space maneuverability, i know it's zero gravity and all, but even with the strongest boosters and engines available to me it's still hard if not impossible to avoid hitting everything since there's no right timing or the ability to see it comming first(meaning those massive satellites that float in a wall around Earth).
