Fairly fine adventure game for the DS.
The graphics are pretty cool. The sound/music is okay, but it gets a bit tedious after awhile (it always changes when your going to fight an enemy; so that might get annoying after a bit).
The play control doesn't take long to get used to. At most 30 minutes.
The save situation though kinda sucks. You could mess up about +30 minutes of work (er ah, playing aggravation). And then it becomes tedious. Also, if you make a foolish mistake like dragon travel to cave, but guess what, you can't get out of it using dragon travel, your sunk there too (like last night I did that, and it wiped out +45 minutes of hard fighting/aggravation).
And although, there is very little replay value, I don't see you getting through this game in 5 hours (unless your using cheat codes). I specifically said to myself one day, "you've been working hard with data entry training + WAL*MART, you deserve to have total relaxed day." And so I played this game from start to finish all day long, and still couldn't get through in one day. I played from like 11am-9pm at night (with meal, snack, and stretch breaks in between, but still). Its more like +10 hours of playtime.
So overall, if your looking for a game like the Harry Potter PC games, then I wouldn't waste my time hesitating whether or not to get this game, because this game is the best match (and you can probably get it for decent price now). If not, then I'd probably rent first.
