Tomorrow I'm taking the plunge and buying this again.
I tried it for about an hour a few months back and did okay but got pissed when a Silver membership didn't allow other player interaction and returned it.
After scouring many a forum, I'm of the opinion that the game is beatable offline.
Discussions, tips, your opinion on the game?
Don't worry about spoilers, forewarned is four-armed, or something like that.
