I think it'd be a good idea to have it WW3, or 2235.
Reason being is that alot of people would MUCH rather have a Earth Empire vs. Alien/undead Reich, or Humans vs. Robots/cyborgs.
Did I mention no worries with historical accuracy? Yes, mmhmm. Yep. NO problems.
I mean, it's classic. I'd rather have a heavily armoured infantry guy in a battle suit with a 12mm autocannon then some idiot with puff the magic dragon, or old ross shooting at wild bill or Physcho cho. Mmmk? Mmmk.
I think the one tier is the better idea. I mean, it was way better. No reasoning. Just liked it.
Autocannons, supply conveys, running out of ammo, a 72-hour storyline campaign... Something DEEP. And.... Hard. And.... Incredibly challenging, and long. Something I can enjoy for DAYS before I finish it.
Here's an example:
Commonwealth (these guys are the starting campaign faction)
Attack
A3030 attack gunship, T07 troop dropship, SS-50 stinger command ship, 605-BR Armadillo tank, AAT-292 Flycatcher tank, CH-KN Bipedal assault tank, SQ-WK Bipedal APC, AP-01 scout walker, AP-26 battle suit, HV-Y50 heavy assault suit,
Scout, medic, gunner, combat medic, marine, shielded marine, SEAL.
Defence
9mm autocannon, 12mm autocannon, 14mm cannon, 16mm striker, Sand bags, barbed wire, mine, boobytrap, spike trap.
Supplies
Ammo, Med-packs, upgraded KEVLAR, upgraded machinegun, upgraded bullets, Books, movies, entertainer, base camp, supply truck, supply gunship, orbital hyperspace station.
Maybe 3 factions?
Outworlders (basically aliens)
Attack
Ythir (Fighter craft), Vhathne (Shielded ground armour), Dah'rte (Something like a slug with a laser cannon on its back), Scyk (This big guy with blades for forarms), Bhuldos (stereotypical alien carrying laser gun).
Defence
Thyrmoloth (Kind of an auto-turret.), Vythops (hive mind, it takes over Commonwealth infantries' minds AKA convert), Chyrthok (Basically a big laser cannon).
Supplies
Hyrto (energy hive, for recharging weapons), Slyim (life hive, for recharging health), Carbett ( supply ship, about the size of a cruiser), Gha'lluhma (Hiveship; the mothership; the boss).
These guys are original!
Araphan Marauders (these guys are a group of BAMF Humanoids)
Attack
Strike Fighter, Orbital transport, Shielded fighter, Lich-class detachable missile pod, space marine, medical droid, raider, shield carrier, PlasmaBlade Juggernaut.
Defence
Arbitor shield-piercer, Helios autocannon, Genii style heavy artillary.
Supplies
Ammunition shuttle, Medical shuttle, back-up laser rifles, Back-up Cynaptis gel, back-up ray-shielded armour, Orbital cloning facility, orbital shipyard, Orbital Raider-class hyperspace station, The Nemesis (Boss ship)
Oh mah gawd, this is fun!
Genesis Red (these guys are unlocked to play after the campaign is finished)
Attack
Arachnid artillary, Arachnid flak turret, Arachnid autocannon, Hybrid (intelligent gel inside an armoured suit), Skybrid (computer-driven flying armour), Bladewielder, Blademaster, Sentinel, Lord Jadakk (elite unit, half-boss, half heavy armour).
Defence
Guardian-class cannon (Laser cannon, heavy damage, rapid fire, hits everything)
Supplies
Hade's Brim (boss, it's a big fortress with Guardian-class cannons all over it, and spawns Lord Jadakk ONCE a battle)
The Commonwealth is a post-apocolyptic government ruling Terra, and the Sol system. These guys have alot of units, but aren't very strong, or fast.
The Outworlders are aliens. They came through a wormhole approximately 1.3 lightyears from Terra. This caused the apocolypse, since alot of the Earth's surface was swept into the wormhole, leaving China and Russia... And Japan. It took the Outworlders 52 years to reach Sol with their battered fleet. They quickly took mars, and attacked the moon.
Araphan Marauders also came through the wormhole, but arrived at Sol 16 years before the Outworlders. They were relatively peaceful, only making a few raids on Mars for supplies. They originally came from Terra, but left in the year 1631 B.C. from South America. When the Outworlders attacked the moon, The Araphan leader saw it as a threat to the homeworld, and declared war on both the Commonwealth and Outworlders in an attempt to keep them away from Terra.
The Genesis Red were from Germany, before the wormhole. a chunk of Terra was torn out, and taken towards the wormhole.
ost of it was swollowed up, and sent to the recently- discovered galaxy Chilestrae, and was annhilated by the battle fleet of the Outworlders, since that's where their homeworld was. Anyway, the wormhole closed BEFORE the east half of Germany was destroyed, so a few humans survived. 47 years after the disaster, they had built a cyborg fleet, and headed into Sol space, on chunks of terra they called "battleships." They arrived 3 months into the war, and allied themselves with the Araphan Marauders.
So this is my idea. Took me 3 freakin' hours to write that up, so read it. Fanks.
