Fallen Order was good. Nothing original in terms of game play or really even story. However, it was solidly executed and its characters were reasonably interesting once you got into the game. The 2nd Sister was especially good and she serves as the primary antagonist. There would be a lot to talk about but I'll leave it spoiler free. The game does have some surprises in it and the worlds feel larger than they are. Its set pieces are absolutely stunning and it ties in well with Star Wars lore. The music, sound and feel of the game are spot on. The designs of some locations are taken straight from their source material.
The protagonist feels a little flat at first, but the more you experience the game the more he fleshes out. He reacts in realistic ways to things which remind him of his past. He doesn't develop as much as say Starkiller did, but he's a more grounded and realistic character.
My biggest complaints is relatively small, but here they are:
Lightsaber customization, while excellent doesn't allow you to stick to a single saber hilt, or run dual sabers all the time. There is one more issue here, but it contains spoilers.
Parry window timing is actually connected to your frame rates. This gives you 0.016 seconds to react at the Grandmaster difficulty if you were at 240Hz.
Character customization is a special low point. I understand the character has a fixed face, gender, etc. which is all fine. However, you can only change the color of his base outfit or remove and customize the poncho. By customize, I really mean picking a color pattern for it.
The game really needs a quick travel system. While there are some short cuts that can make getting to the Mantis easier, its a slog most of the time and these are not always available at every point on the map.
The map sucks. It's a solid design but it does a very poor job of showing you how the different sections connect and by displaying everything at once without filtering out other levels, it can be confusing to look at. These minor adjustments would have made it much better to use.
Cal's Force powers do fit the game's mechanics, however, you end up wanting more at times. You can't mind trick or anything like that. He also has what is possibly the worst Force jump of any Force user we've ever played in any Star Wars game. It works well but he can't jump particularly far.
Little things I've noticed:
All of the Clone troopers seen in flashbacks are all voiced by the same actor who voices them all in the Clone Wars TV show.
Plenty of references to earlier material such as the Clone Wars are in the game. On Dathomir, you learn of an "armored warrior" who wiped out the Nightsisters which is an obvious reference to General Grevious.
Force echoes tell various mini-stories of their own, sometimes interconnecting.
