Like many other Massively Multiplayer Online Role Playing games, Scarlet Blade is a game in which a player designs a character, both physically, by selecting options that define their characters appearance, as well as functionally, by choosing a class (damage dealer, tank, support, etc.) to play. That character is then launched into a world in which they will kill monsters, level up, collect loot, and craft items. Nothing exceptional going on here in terms of the conventions of the genre.
The one notable difference between it and other games of this sort, though, among all of these fairly standard MMORPG conventions exists in character creation. Simply put, there are no men.
