You should really just look into 10six.... let me take you back to 1999 and my first mmog.
In 10six the world was divided into "camps" each was a certain space w/ randomly generated terrain and 5 hotspots where you generated resources. When you started you joined one of the 4 major corporations that were battling for control of the planetoid Visitor. You had one camp, and some basic stuff.
-Your avatar was fps, you had a hoverboard, you could jump the aiming was fps and you could equip armor guns gear (grenades, toxic bombs ect) on your avatar. You also had to carry TU which was the only resource that powered everything. All weapon fire required tu.
-Your army (rts) was made up of "rovers" this were rudamentary ai, they would fire at things that got into range and chase them once they started firing. That was it. You could have them patrol but that never worked perfectly. When in a camp w/ your rovers you could select them tell them where to move, what to attack ect ect. Each rover was a mass of seperate items combined: Rover/Armor/Armor mod/Weapon/Weapon mod/Rover mod. We'll get to items in a second, there was a allot of different combinations lets just say.
-In your camps you built defenses, using primarily turrets, but also mines and walls there were many types of turret that used different weapons (artillery/direct fire/anti avatar/anti rover/flying turrets ect). One of the most important aspects was being able to setup defenses that would slow down your enemy as well as traps to kill them.
-Items were obtained by selling your TU (the game's resource) to your corporation, each camp could have 5 wells, placed on the hotspots they would mine the TU so you could make money. Once you had sold the TU you could buy "jitter packs" from your corporation which would give you a random assortment of items to be built. The items had various classificatoins (rare/limited/common) You would recieve 1 rare 2 limited and 7 common per pack. You could go to no-fire UN camps to trade or buy from other players.
-When you killed an avatar, destroyed a turret, or a rover all the jitters carried or that make up the thing you destroyed would be dropped.
-Everything but your main camp (chosen by you) would be open to attack 24/7, your main could only be attacked when you were online. Therefore all players were forced to join Multi Defense Networks (MDN) the clans of the game. Each clan had a max of 20 players and it was paramount that each person be active in fact the more active the better. Wars were all about discovering the other MDN's weakest hours and exploiting them. Attacking multiple camps at once making it hard on defenders to respond or doing fake attacks and withdraw wasting the defenders time teleporting to camps only to find them empty while you hit another camp w/ your rover army.
-You could "newbie lock" a player, by destroying all his camps and his main, he would loose all of his stuff unless he realized he was going to get locked and started transporting his stuff to friendly camps (which was rare and hard to do). Once he lost his last camp he would have to start from scratch, claiming a new camp and rebuilding his empire.
-This was the most hardcore game ever made, no game will ever be this hardcore because it literally required you to play a absolute minimum of four hours a day. Most players found themselves playing 8+ hours per day during wartime. The best MDN's were always comprised of skilled players who were very active.
If you want to try it out it still exists in a ghetto player run form here:
