-Six races; Hylian, Zora, Goron, Rito, Gerudo, Twili
-Class-based system with hybrid classes for more skill options
-Warrior class is standard DPS with some tank options sprinkled throughout the skill tree.
-Knight class is standard tank, pretty much the reverse of Warrior
-Rogue is the lighter DPS class with stealth and persuasion tactics
-Rogue can spec into Sheikah-style Ninja class at Lv. 20
-Warrior could spec into Knight, or higher-damage Berserker
-Obviously there'll be a Mage/Wizard class
-Hybrid Warrior/Mage spec can unlock Spellblade class
-All classes can wield any weapon type, and can dual-wield single-handers, but some weapons are better than others for a certain class
-Max level is 35. Will go the Guild Wars method of skill-based gameplay, neutering the need to grind.
-All progress in the game is quest-based. The more quests you complete, the more experience, gold, and unlockables you obtain.
-You can go anywhere at any time, but be wary of dangerous areas. They are not impossible to traverse, however.
-Story is Ganon has found a timeline where Link and Zelda do not appear. The denizens of this Hyrule take up arms to combat the threat of the looming darkness.
-Endgame is the fight with Ganon, but is event-based and requires a party of 16 people to start it.
-Once defeated, Ganon will be sealed away for a time, until the next event starts where he reawakens.
-All 16 players will be deemed 'champions' in a hall of fame, and be rewarded upon repeated attendance to the event.
