the game give you complete freedom on role you want to play. how you achieve is up to you.
it is always like this with open-ended games. you have so much things to do that you dont know where to start and you are constantly sidetracked by something else. while you are trying this and that you lose focus on your "big goal"
i've started 2nd time into game (i play solo). 1st time was before engineers update and i didnt liked it much. rewards for missions was small, control of the ship with m&k was meh, i didnt had a clue what i am doing and i just left it for quite long time.
now i have
this. ship control is far more pleasant. missions are more divers with a lot better rewards. after i've maxed out sidewinder i've made a little resurch on what to be my next ship and i've started picking highest reward missions that i think i can complete. got money for cobra mk3 and it's initial outfit w/o hassle (iirc i couldnt make it till mk3 1st time). got rank in exploration and combat and half way to next rank in trader. in mean time increased rep with some minor factions and feds i think if i join fed i will be eligible for rank up straight away. then i've checked what are those engineers all about. i've decided some mods could be useful so i am now working on unlocking independent engis. weapon guy was easy but hull, armor lady is a bit boooooooring (at least for me). have to mine 500 ore. i've bought type 6 set it up for mining (B refinery, scan and gather drones etc) but after 8-10th asteroid i get sleepy so this one goes slowly. i do make some money from selling ore but missions are far more effective (i havnt looked for high value mats or mining missions thou)
i've havent been into powerplay but from what i've read about it give you a opportunity to influence galaxy politics (should you are interested in this, i am not so far). not 100% sure on this but i think after initial setup of powerplay changes in the faction influence is fully community driven and randomness in this aspect comes from strategical and tactical moves of community guild/alliances that are big enough to influence galaxy map.
you also have weekly community goals that give you nice cash rewards (fight and trade missions in specific system) where you join your effort with the rest of the community and yes it is available in solo mode too.
but they seemed like fancy packaging to make the grind a bit more meaningful... am I right or wrong
grinding is there but it isnt as mandatory as in other mmos. there isnt best ship and bigger/more expensive doesnt mean better. if you find reasonably priced multi role ship works ok for you dont need to spend for bigger one. just max up all modules and enjoy your time.
There is one thing, even with Powerplay, that still seems amiss, and that is persistence and 'presence'
well it depends on what you expect from the game. it is just space ship flight sim. everything else is added to give you some reason to fly from A to B. what you will get from the game is up to you. if you like you can play role. if you like you can try to influence galaxy politics. whether you will be noticed or not depends on the time and effort you will put on this. frontier are trying to build alive galaxy which in some aspects is fully in other partly driven from community. how successful this will be is yet to be seen.
