I'm not keen on their current Disney-meets-Ghibli-style direction. That's more of personal preference than giving them high-five for their business accomplishments. I will say that they're certainly about as reliable as Capcom for generating sequels (for all but Dark Cloud anyways).
Haha. Dark Cloud... some Level-5 fans never got over that one.
It doesn't concern me that much if they do a 3rd game or not personally.
