This game has decent learning curve and can be rather exciting in the early on.....but, once you have acquired enough money to build a decent ship (about 10 hours if you don't google it) there's really not much to do. It is a problem with all sims, once you learn the ropes you pretty much coast. Now i'm not saying that the game isn't enjoyable, it is. Its just not very deep. So if you enjoy Newtonian Physics and Like a decent build tree then by all means have at it. But if your looking for a relationship with a Space Sim might I recommend Any of the X series (except the last two).
