I was thinking about The Secret World, but I feel that I left The Old Republic "unfinished." Plus, this will give some time for The Secret World to work out all the bugs, before I give it a real whirl.
(Though, there is something about being in a game at launch, discussing and writing about it early. Before the game becomes solved.)
I ended up deleting all my alternate characters, and only transferred my 50 Imperial Agent to the new high-pop server. Sadly, my name was taken, so I had to use an different name. I decided to start a new Jedi Knight to ease back into the game.
I think that TOR has improved by leaps and bounds. In particular, their performance optimization team has done a spectacular job. Basic engine performance is miles better than it was at release. As well, there are lots of people on the new server, making the game seem vibrant and alive. Lots of chat too, even with TOR's flood of system messages.
The Legacy system has been fleshed out, and has all sorts of options. I haven't really explored much here.
I haven't really gotten a chance to try the group finder yet. My 50 is DPS, so the queues are very long. Plus I don't really remember how to play her, so I'll have to re-learn everything. I'm also not too sure what the path in endgame is like.
Still, I like the improved TOR so far. We'll have to see if I can get into its endgame, though.
