Yeah, the game certainly drags out the start alot more than was necessary (although I'm not complaining). Since there's only so much they can do within the anime timeframe it was a reasonable progression. But then, it wouldn't really make a heck of alot of sense to those unfamiliar to the series.
I think the pacing and development of the next few episodes will be much more important than what was in this first episode though. Can't wait till next week already.
