Its a poor launch and with ever new Phantasy Star they release less and less.
The cash flow is low and you could say this is balanced by the opportunity to get a the rare Fixa presets that are droped via RNG... however they don't drop enough to justify the rate and what you have to do to level and augment them within the system... meanwhile they poor into your inventory and take up a ton of space which is shared with PSO2's inventory which we've been given no hint of whether that stuff will be useful or not in NGS ever so you just sorta have to hold onto it and take up space.
Btw... the division between what is and isn't transferable is dumb. All the materials aren't used, the scape aren't used. You have no housing, etc... this all just dumb story wise, gameplay wise, and developmentally. There should be some way to convert the materials, scapes, etc. And with regard to the Aliance and Personal rooms, they shouldn't be locked out unless you go to classic. That's dumb. It makes me waste time teleporting x to y to z for no reason. The thing that allows me to go between x and y is the same place that allows me to go to z from y so x should let me go to z mechanically and why are you removing a feature like that? Even when the inevitable NGS exclusive rooms come they should just be another teleport location from the teleporter and shouldn't lock out the room for other game... also... the room ticket is locked out which dumb as well. And hopefully it doesn't indicate that Sega is going to try to make us pay twice for the same features.
That being said, my main complaint is that NGS is lacking content... and by content I mean story and quests. The story so far is "Hi you came from space. We don't know what's up but there's these things that also come from space and attack us. You've forgotten your memory, but hey your type is good at fighting those thing so come live with us and lets figure stuff out... Hey you should be in the army. BOOM. Hey we need to you to join the army with these people you barely know and please help us and protect us. Oh hey the guy who was supposed to help you learn the ropes is lost. Lets go find him! Congrats on finding him. We want you to go to a different city now." And you know what, that's fine and all for an opening. The problem is "hey help us" and there is no tasks to actually go help.
Alfin has more missions for you to do than all of Aelio Region has had for you to do. Sega needs to add in a whole bunch of side quests to make it feel alive, and not just make it a tutorial. That's what the first part was, the Region isn't supposed to be v.v Functions being locked out until you go on missions is also dumb unless there is a real story reason for it which there isn't and there just isn't story here.
Sega has removed lots of better ways of doing things in favor of streamlining some of it. It used to be in PSO2 you go through a zone and you can interact with a tablet which would give you a piece of story which made sense. A little difficult to see if you got everything, but it made the game more adventurous. They removed all of them, and gave some of them (i don't believe all) back via you just clicking a button, which while yay i can now know if I have all of them, I don't get the fun and excitement of discovering things in their proper context... oh and the story stuff isn't even in the right order in that menu option sigh Now with NGS they have removed characters with stories that you can interact with, team mates that you can call upon, etc. I don't care about Aelio so why would I care to protect anyone there at this point. I don't even spend enough time with the main characters that are being thrust upon me by the story to care about them. I can't take them out adventuring or anything like that nor do we get cutscenes that shows their story so its a lot harder to be attached to the world and game.
Along with the above also comes the fact that it becomes harder to level those other classes. You pretty much magically jump from 1 to 7 if you do what Sega wants you to and then you get stuck grinding levels and/or using the only significant exp to get ex-cubes which you need for crafting, to max your weapon so that's a disincentive as well. Having proper side missions and such would fix that problem.
Ultimately... the real issues with NGS and PSO2 for that matter, is that it is too Casual for Hardcore players and too Hardcore for Casual players and it is such in the wrong ways which annoys all sides. And some of the hardcoreness is not even being real hardcore, it's a matter of you are on a network based game which means you are going to lag and that's going to cause all those precisely timed elements to be very difficult to really pull off, but oh well. that's Sega and Phantasy Star for you... brilliant elements in mixed with a bunch of really really really bad elements that they think help them make money or be secure or whatever shrug
