One may be a bit suspicious that the game advertises so many features, but it does execute them very well.
First off, I recommend reading the only english speaking guide as a good primer on what settings make a good beginner game. Also, sell your starting shields (if your ship has any) because they are complete crap that takes up too much space at the beginning. Shields in this game only block percent damage, and starting shields block next to nothing. Missiles/frag cannons are very good weapons early to mid, though missiles must be manually reloaded. Finally, find a pirate base and join them for a free, VERY good ship. It doesn't matter if you don't want to go pirate, you can always go grab the ship and just fight dominaors for pirate favor/backstab them and hunt them down. Ironically the one segment of the game that is the most obviously advertised, space combat, is also the most infuriatingly obtuse to figure out without the help of a guide or google.
Starting tips aside, the trading in this game is dynamic and well done. Planets each start with governments/econmies that are geared towards importing/exporting certain goods, and events such as famines, pandemics, or a change of government will occur that shake up prices. One can make a fairly good amount of money by keeping check of the news and moving large quantities of goods in a freigher. you can own multiple ships, so if you have a fancy fighter you can just park it on the planet.
Speaking of which, in the lower left tab quests, assets, and any news blurbs you flagged are kept there for your future reference, making it easy to keep track of assets you store on different planets/stations, or where you were supposed to ship your cargo hold full of medical supplies.
Quests are offered at government centers on each planet, and are by and large FedEx delivery missions. Asking for easier/harder missions only affects the amount you earn and the amount of time to complete the delivery. You are paid whenever you complete a delivery, making it very easy to simply FedEx you way into riches (if you have the patience)
Some quests end up turning into text adventures (and are usually indicated rather obviously as not your standard delivery). Judging by the ones I've played, the text adventures are rather well done and fair. In the event of player death or failure, you are rerolled back in time to try again/give up whenever you want.
The RTS segments are somewhat simplistic, with the complexity coming in purely through how you choose to build your combat units. Simplistic doesn't mean bad however, and for the most part they were rather fun. With the glaring exception of several missions that are hellishly difficult.
What I find most attractive about the game is its sense of immersion. Events happen around the player, and it is up to them how to respond. The Coalition, Pirates, and Dominators will all launch attacks/defend star systems, other Space Rangers will fly around doing their thing, more Rangers will be recruited to expand/replace losses. Research into better technology will happen (and can be funded by the player), militaries will build new ships/garrison systems (can also be funded), and overall it gives of a good sense of "Hey, you aren't the only hoshot out there getting things done". Heck, on the easier difficulties, the Coalition (the rather obvious good guys) can very well defeat both their enemies without any player intervention. (It will be a VERY long game, with the player doing absolutely nothing in the mean time)
