This game isn't terrible, but you pretty quickly see everything there is to see in the first few hours and everything else is a grind from there on. Each system, while very pretty, is basically the same and so there is no real motivation for exploring. The side missions fall into a handful of categories, repeated many times with just different systems to visit. The trading is uninteresting and because of the way the upgrades work, there really isn't anything to spend your money on anyway (also, it stops showing you how much money you have once you reach 9,999,999 credits).
The story is okay, if very linear and uninspired, with a rip-off ending and very little challenge. Also, once you've finished the main story, there is no motivation to continue.
The voice acting ranges from passable to absolutely horrible with, unfortunately, the main characters falling into the horrible category.
Unless you are huge space-sim fan, you might want to spend your money on something else.
