I'm suggesting a mod for FAF: Draft & Skirmish.
In this mod, each players will be given the opportunity to purchase a group of unit among a predefined selection, a specific number of times. Each choice comes with major selections followed by minor selection. After choosing their units, the skirmish will begin with units placed on each side of the map.
-For the first major selection, Player 1 can choose between: 30 T1 tanks / 40 T1 Mobile AA / 30 T1 Mobile Artillery / 30 T1 interceptors / 20 T1 Bombers / 10 T1 Firgates / 10 T1 subs
-Player 1 can choose among the same major selection
-Player 2 can choose 1 minor selection: 15 T1 tanks / 20 T1 Mobile AA / 15 T1 Mobile Artillery / 15 T1 interceptors / 10 T1 Bombers / 5 T1 Firgates / 5 T1 subs
-Player 1 can choose among the same minor selection
After that, the skirmish starts and players manage their units to victory.
Next, a new draft and skirmish will be played with a different tier of units (T2, T3...). For example, T3 with navy and air units:
3 Major selection followed by 2 Minor selection:
Major: 1 T3 Battleship / 1 T3 Battlecruiser + 1 T2 Destroyer / 4 Destroyers / 4 Cruisers / 6 Shield Boats / 10 Torpedo boats / 8 T2 Subs / 36 T1 Firgates / 24 T1 Subs / 24 T3 ASF / 40 T1 interceptors / 30 Fighter Bombers / 30 T2 Gunships / 12 T2 Torpedo Bombers
Minor: Just the same as Major but with twice less units (2 Destroyers / 2 Cruisers / 4 T2 Subs...)
if Player 1 is the first choosing during the major selections, Player 2 would be the first choosing during the minor selections. To summary, it would looks like: M1-M2-M1-M2-M1-M2-m2-m1-m2-m1. The last selection for each player could be hidden from the opponent.
I am planning to edit this post to add more details later
Alternative mod: ACU income
Each ACU generates a specific amount of mass and energy (ranking up during the game). There is no mass spots on the map and it is impossible to build mex or mass fabs. However it is possible to build PGENS to provide extra energy. For example, ACUs would generate:
t = 1 min - 2 mass, 20 energy
t =2 min - 4 mass, 40 energy
t=10 min - 20 mass, 200 energy
t=11 min - 24 mass, 240 energy
t=15 min - 40 mass, 400 energy
t=16 min - 46 mass, 450 energy
t=20 min - 70 mass, 650 energy
t=21 min - 77.5 mass, 775 energy
t=25 min - 100 mass, 1000 energy
t=26 min - 110 mass, 1100 energy
Without territory control, this would provide a (very) simplified FAF experience, where players can focus only on building their units.
