I got to Tatooine last night with my Sith Inq. and I am loving the Story for it so far. I have loved all the plannets so far, but Nar Shardaa was horrid. I just could not get into it at all and pretty much just did my class quests to get the hell off of it. It was neat at first, since for me I went through Korriban, Drumand then Balmorra so it seemed like it would a good change of pace, but just corridor after corridor got really boring to me and I wish there was more variety.
I think the problem with it is that it is just all the same. I would not of mind if like 70% was city, but some other enviroment since it is a "planet" and all was also available to explore. I mean, you can apply that to all the planets since they only use a small section of each planet for the game area you play in.
Tatooine however is just massive and nice and open which I do kind of like more. The nice thing about this game is that each of these are planets and they can add more areas to each of them to expand the game even more, especially for starter planets, they could add something ot the other side of Korriban which is a mix of dessert looking then it slowly transitions into a near ocean looking area or any enviorment type....a spooky looking forest area would be neat.
