Not right now it isn't. It's actually deathly boring, apart from the routine battles against rogue forces. Of course, I fully expect that *something* is going to happen to break up the monotony, but until it does I don't recommend BT as a way to escape boredom.
As I said, still licking its wounds. The current situation is extremely unusual.
Personally, I blame character mortality. We'd totally have bashed back on Riombara for all their foul play if the invasion hadn't totally crippled us... They still owe us a royal's head, after all.
