After 4.0 I have absolutely loved every minute of this game, I subscribed to get all the new expansions and it's even better! - I used to play as preferred before that but it was a bit slow, now I can jump right in and it's really been the highlight of games this year for me.
I loved the Imperial Agent story line, I love how the voice of her is the voice of Hawk from DA2 - great casting! Been playing the expansions and KOTFE with her.
I love all the side characters, all of the different stories I've played so far are also very compelling. I've played parts of Knight, Consular, Agent and Smuggler. Agent is main because of the moral greys and character development - I role played a bad agent turning good over time.
I saw a review of this game on a show called "Good Game" and they described KOTFE as like a star wars telltale game, it really is, and it's basically BioWare at it's best.
I am quite poor so I can't subscribe for a long time - so I've found it very fair and kept me playing given the content you get for subscribing, my only suggestion would be to give extra perks (rather than gate stuff away) to subscribers who can afford to keep subbed for long periods so that you make more money and keep making great episodes like KOTFE has so far.
My only complaint would be the loot boxes, I have deep ethical issues with using gambling theory to get money off people. I think cash shop for items is absolutely fine, it's the random items you can't buy outright I find disheartening.
This is grade A Bioware storytelling, I know I probably sound like a PR person but I'm genuine about how awesome this is, I love star wars roleplaying games
