In Radiant Mythology 3 there is no world map to traverse across nor are their multiple towns as in the mainline tales games. The main town is your central hub where you will then be sent to far off locations to to do a variety of tasks with a group of companions from past tales games.
The game uses a slightly modified version of the Flex Range linear motion battle system first used in tales of the Abyss. This system allows for more flexible movement and the abillity to move in any direction.
In the tales series Artes are used to dish out extra damage aside from typical character combos. In general these abilities are learned over the course of the game by leveling and in some cases side events. Moves are usually designated to one button and 4 artes can be mapped Linking these moves with your normal combos is the bread and butter of the Tales series in terms of being offensive.
