-Job classes
-No traditional exp. Bosses drop level up crystals that you can spend on skills you choose. Every few of these used also raise all stats.
-Battles reward SP, which can be used to level up specific skills.
-HP/MP is refilled after every battle making it so you actually use your skills and don't have to save everything for the boss at the end of the dungeon.
-All enemies visible on field and do not respawn unless you fully leave the zone.
-Most characters by the end of the game have options that let you build them in one of a few ways that vary greatly between the characters. For example, one of mine is a speed demon at this point that gets 3 turns before most enemies can act once.
-Reward Board - a board game like thing where you can unlock squares by completing tasks in the field.
-Crafting for upgrading weapons and armor (but not crafting NEW weapons or armor)
-Crystals for socketing
-Mechs
