Playing Casual mode kills one of the best parts of the game, the tension you get when you've been fighting through several FOE's and you don't know if you'll make it to the town(which is silly because you can always have a rope to get out)
it's amazing,
Time constraint, that's my only excuse. I'll get to play the game a day or two during the week, possibly, I'd like to maximize my playtime. Casual does just that for me.
