So I decided to play this game on the free weekend pass thing they have this weekend.
It's decent. Not bad so far.
As far as the actual MMO mechanics go, it's not that great. Standard stuff for the most part, but it seems like they made some dumb decisions that make things annoying. Run speed is slow and it feels like NPCs are spread out to an unnecessary degree. (That may just be because I'm coming straight from Star Trek Online, where picking up/turning in quests just requires hitting the "Hail Starfleet" icon, for the most part.)
I'm playing as a Republic smuggler, so there's a cover system. It's... okay I guess. More interesting in theory than in practice, but it's alright. The game needs to be slightly smarter about letting you get into cover, I've found. I did appreciate the attack where you toss an explosive onto a guy and then shoot it to blow it up. Really satisfying.
I do appreciate that it appears everything in the game is voiced. I do wish you got more dynamic scenes than "Guy talks, then you talk, guy talks, you talk while somebody walks up in the background, guy talks, new guy talks, you talk, scene ends." Shot. Reverse shot. That said it's still much better than most MMOs in that regard, just not quite as good as other non-MMO games.
All in all, I'm enjoying it, but I don't think I'd bother with paying a monthly fee.
