How Long is SOTN?

I got Symphony of the Night a while ago on XBLA, but I never really bothered to play it, with all the other games taking up my time. How long will it take me to finish this game. Also, how hard are the achievements, since I'm kind of a completionist.

You can beat it in a weekend if you want to get the bad ending.  Mind you, the bad ending isn't horrible - it's certainly better than the "super bad ending," which is, of course, death - but it's not the best you can hope for.  For the best ending, expect about 20-30 hours.

" The achievements aren't hard at all, there is the tedius map completion achievement that can be insanely annoying because you won't be able to figure out what tiny little room you haven't explored yet, but the rest are all easy providing you know how to get to the real ending and such. 20-30 hours is a HUGE overstatement though. I'd say 10 for the good ending, MAYBE. It depends how many times you die and how lost you get, but I didn't think SotN was that hard personally. "
