Overall I enjoyed it. It was worth the 15 dollar sub in my opinion and I'll probably stick around and do a Class story or something before my sub runs out. That being said I do have some complaints. Keep in mind I quit after Chapter... 6? of KOTET. Whatever the last one was at launch. Never resubbed to do the rest, so I replayed through all of it as a refresher.
1. So this isn't a new one, but jesus christ is the engine bad. Like some of the maps like Ossus and Onderon are beautiful and the lighting in the last chapter of KOTET? Ugh so good. That being said the pop in in most of the cutscenes is horrible and the game runs like ass. There was a recent earnings report that said that SWTOR has made 1 billion for EA so far, so I hope they keep supporting it but I worry that this game will eventually break due to how horrible their engine is.
2. I really started to miss the structure of the 1-50 experience where you're put on a planet to explore and you can do your main missions, but there's also a lot of side missions that give you context into the world and it's politics/culture. But you really just end up going through Ondaron and Mek-sha in the story missions and not really getting much in the way of side quests. KOTET was so fucking linear you were just jumping around from planet to planet running down narrow corridors. They improved this in Ossus and the Onslaught zones, but they just kinda wind up being large and... empty at least in terms of reasons to explore. I am pretty ignorant on the structure of SWTOR though so maybe I'm wrong about this part.
3. It's short. It seems like there are giant gaps in content in SWTOR and while I am only a tourist, I could understand people waiting all this time just to get a story that lasts 2-4 hours and being upset. The quality is definitely there though and I'm definitely excited for the future content.... whenever that drops.
