Subject: Tech Levels in FT/MT

Our Campaign Tech levels are as such:

TL1: C Batt, Submunition Rack, Hulls up to Mass 22,
TL2: B Batt, Missile (Basic), Minelayers, Shield-1, Hulls to Mass 32,
PDAF TL3: A Batt, Missile (EMP), Basic Fighters, Pulse Torpedo, Hulls to mass
50, ADAF, Needle Beams TL4: AA Megabatteries, Advanced Fighters, Wave Gun,
Hull to mass 70, Missile (Needle)
TL5:Dual  Combination Fighters (ex:Fast-Heavy), Nova
Cannon, Cloaks, Reflex fields, Any Hull size

Everyone started out at TL1 for setup with 10,000 points to build his
entire fleet (including Orbital Shipyards/defenses) A player could
pay a one time fee at startup to boost his tech level by paying 1,000 credits
per level (combined). So, for instance, if a player wanted to
start at Tech 3 he paid 5,000 of his 10,000 startup money.(TL2-2,000
+ TL3-3,000) Obviously, players only Buy advanced tech at startup
after careful consideration. Every turn (month) players receive 1,000 credits
for his homeworld plus 300 credits per colony plus 100 credits per outpost as
revenue. the player then pays a flat fee of 10% of the ship's build cost as a
maintenance fee to support his fleet. In order to advance Tech levels during
the game, a player pays an amount equal to the Tech level x 1,000 to advance
and the Tech
level becomes available after 1d6+TL months.
So far, it is working rather well!! Mike Wikan
