(Spoiler free-ish)
Just beat this game tonight after binging on since Friday night.
I can honestly say it blew my expectations. Characters like Jessie, Biggs, and Wedge were fleshed out which added more to the story. There are sidequests, but not a lot to bog you down and were 90% easy to complete (the other 10% took some determination). Some areas in the game that were straight shots from one to another, they added new elements and expanded on those area to give it some size (just looking up in the slums gives it a "holy hell, this city is huge" feeling.
The music was fantastic. Going through places and hearing renditions of songs past was just fantastic.
I put in about 45-ish hours in the game and I'm yearning for me. This just brings me back to almost 23 years ago when I first played the original. I can probably replay this game again, which is what I'm going to do this week since I have it off for vacation. Any of those who have a PS4 owe it to themselves to play the game.
