So far we're gonna have:
Gold System (harvested from mines like in Warcraft 3)
Lumber System (harvested from trees like in Warcraft 3)
Population System (from houses etc. like in Warcraft 3)
Gold Bounty System (like in Warcraft 3 but not just from creeps, from player units and buildings too)
Undead System (certain Undead races will transform living units they kill into Undead units for themselves)
HP System (like in Warcraft 3)
Mana System (like in Warcraft 3)
Damage and Defense Type Systems (like in Warcraft 3) -If It Doesn't Become Too Complicated
Remains System (gotten from a special bounty for Black Sun race only)
Remains Bounty System (like Gold Bounty but gives Remains instead)
Life Shard System (harvested from trees {only a little bit} and special bounty)
Life Shard Bounty System (like Flesh and Gold Bounty Systems but gives Life Shards)
-Maybe (post how u feel about it)
Platoon System (kinda like in Godfall Chronicles {Warcraft 3 Custom Campaign} where u just need to move one unit and others will follow that unit, and that unit is usually a slightly buffed version of the other unit with some exceptions, such as catapults or some mages which come in single unit platoons and summoner platoons where most of the units are regular melee / ranged maybe slightly nerfed and the commander can summon more of them for mana)
all i can think of for now
