After hitting level 20 it starts to get a bit boring, because Scarlet Blade is pretty much your very generic point&click game: Target a monster, press 1-2-3-4-5, move to next target and repeat. Eww.
The quests also consist of "kill monster x times" or "move to location y". At least you can recieve and turn in completed quests on the spot, which saves a lot of traveling time.
The only thing that makes Scarlet Blade different from other mmo´s is the half naked girls.
