Subject: Conversion Factors for Full Thrust, DirtSide II and StarGrunt II

Hello, I've been trying to build a system for smooth transition from Full
Thrust to DirtSide II and StarGrunt. Now with the FMA system out, I think I've
got a working solution. I'm reasonably satisfied that the Space conversion
from DirtSide II to FTFB rules are 1 MASS = 25 CC. This is based on the idea
that a specialized fighter built for ground attack would be Mass 1 and size
three in StarGrunt (see attack fighter in DirtSide II page 53). It comes to
15CC, but it has to fit inside something and be repairable. to
place a unit inside another you need cc space equal to 8/5 * size in CC.
 Size 3 * 8/5 * 5 cc per Size = 24.  Call it 25 for a working number.
Okay now let's try for a conversion for cost. Take this specialized attack
fighter from DirtSide for a cost of 274 plus at least one DFO for 300. In Full
Thrust other specialized fighters cost 6 points apiece.
300/6 = 50.  Therefore the conversion factor for 1 Full Thrust to
DirtSide II is 1 FT point = 50 DSII points. Previously I've published my ideas
for point costs in StarGrunt being on the same scale system as DirtSide.
However, Jon has published some point costs for FMA that we can work from. We
can then use this same system for StarGrunt.

FMA states that a regular trooper armed with a an assault rifle and Partial
Light Armor (D6) cost 59 points. Give him 1 IAVR for 46 and 1 hand grenade for
22 and you get a total of 127 points. A standard Line squad in DSII costs 20
points for 4 to 5 men. Lets take that cost and divide by 4. 5 points per guy.
We get a nice conversion factor for 1 DirtSide II point is equal to 25 points
of FMA points for use in FMA or StarGrunt.

These should be useful numbers to assist those trying to build a campaign
system that spans these games. We should all bear in mind Jon's admonition to
not power game and pencil whip these factors. No scenario will ever be
completely balanced just because the point factors are equal. But it does give
you the ability to gauge how a game should go. You should give the attacker 2
to 3 times as many points to attack a dug in defender, etc.

Okay, we can use this to examine how to integrate Ortillery into DirtSide II.
An Ortillery Battery has a mass of 3 and costs 9 FT points. We can reasonable
convert that each mass of an Ortillery unit is one battery of Heavy Artillery
(18 CC and costs 200 DS points). Its rough but just assume that an Ortillery
battery is three Heavy Artillery Units. All Ortillery units fire GENERAL
POURPOSE rounds. I'd actually make the cost equal to 4 * mass...
