I'll start by saying that when you install this game, you are actually installing 2 games: Phantasy Star Online 2 (PSO2) and Phantasy Star Online 2: New Genesis (NGS). That is why the install size is so massive.
This does come with the perk of being able to use your character across both games, but if you're limited on space, this game will be a GB hog.

Now, on to the game itself!
I'll start with the good:
+Both PSO2 and NGS have amazingly fun combat, but for different reasons. PSO2 has a lot of class and skill variety, and NGS is very fast paced and is a tad more action oriented.
+The character customization is outstanding.
+The music is stellar. Specifically boss themes. They do a very good job at hyping you up.

Now the bad!
-With the launch of NGS, some aspects of PSO2 have suffered and been neglected. PSO2 doesnt have mission pass anymore (battle pass, NGS gets one) and the game just doesnt get content anymore.
-Combat, while fun, needs work. The UI as a whole is atrocious, and really limits what you can put on your hotbar. This is a problem in PSO2 because you get a LOT of skills. Its not really an issue in NGS because every class only has like 4 skills.... its so stupid.
-Every aspect of the UI needs to be reworked. The menuing in this game is so bad, holy moly. Its hard to explain here, but there is just TOO MUCH to it, i dont need to confirm 3 times to join a party... wtf.
-While character customization is amazing, good luck getting anything cool. The player market in both games is broken, and HEAVILY tilted toward paying players. Items are unbelievably inflated in PSO2, and NGS is starting down that path as well.
-ON TOP OF THAT! If you dont have premium (the game's subscription), you cant even put things up for sale, you can only buy from the player market.
-With PSO2 not getting any new updates or content, that means some items are literally unobtainable now. There are some mandatory items you need for Summoner that are literally impossible to get now. So.

Ultimately, NGS is still in Beta / Early Access, even tho the store page doesnt tell you. Might be an amazing game in 1 or 2 years. There is just so little content here now, you can easily get thru all the story content within a week. There is no meaningful repeatable content yet. No interesting quests, no dungeons... Which is INSANELY bad for an MMO, something that is supposed to be designed around player retention. But nope! Log in to do your 15 mins worth of dailies for piddly rewards.
And PSO2 is basically unplayable now days.
