Default Converting HG ships to Book Two

I am pondering what needs to change or be added to convert a High Guard Ship to Book 2.

Drive damage with no letter system just reduce a drive by performance per hit?

Note there is a rough conversion in CT's K'Kree book of 5 hits per reduction, but those ships are mostly 1000 dTons+ in size.

I'm more interested in the other way around: How do we convert from CT B#5 HG to MgT2e HG?

One approach might be doing it the TNE way by dividing the HG drives by percentage tonnage.

So maybe 1000 tons of power plant that say is Power-5, each hit is 20 tons so it takes 1 hit to reduce to Power-4 and 19 more hits before Power-3, etc.

It's not easy, as the design system is quite different.

To begin with:
  • while in LBB2 Jump Drive used to be quite more massive than Maneuver Drive, in HG is just the opposite, leading to not matching.
  • fuel needs for PP in Lbb2 are independent of ship size (and from PP size), but depend on Power number. When moveing to HG, again they don't use to match (and some times by quite a lot)
  • Most HG designs are larger than what LBB2 allows
  • In HG there are many weapons wihtout equivalent in LBB2

So are most HG designs...

Redesign from scratch; MGT HG 2E is not derived from CTHG, but from CT Bk2...

Actually I was kinda thinking along those lines.

1st thought was to follow the implied pattern from book two. In that every 200 dTons of ship adds a hit pre drive number.






Tonnage Hits/per
200 1/1
400 2/1
600 3/1
800 4/1
1000 5/1


At this point I should point out that my focus is on the Adventure class of ships. While Book to is fine a lot of people love the High Guard construction system.

But any hows the other idea is to use a fixed size per hit. 10 tons per hit follows book 2 for Hold and fuel.

Early drafts of T20 used the following scheme:

Hull: 1 per 100 Td
Cargo: 1 per 20 Td
Fuel: 1 per 20 Td
JDrive: 1 per 5 Td
MDrive: 1 per 2 Td
PP: 1 per 4 Td
Turrets: 1 per each turret or barbette
Bays: 1 per 10 Td

Armor wasn't sloughed off, so it was T20 standard Damage Reduction AV;
Weapon damages 1d per USP factor, sides by type of weapon.
Works great small ship, but too many hits for anything over about 5KTd to play out.

Cool, but now I am going to have to go read that rule book.... When we were playing it I really didn't read much more than Character gen...

I was thinking on Hull to keep it in line with the 1 per 200 tons that I mentioned earlier, but with the number results that are Hull maybe 1 per 100 isn't a bad idea.

I still thinking book two.... But,.... Not a good argument either way.

Concerning Drives:
You could extend the drive/plant tables beyond the standard A thru Z letters. Mongoose did this with drive letters AA BB CC DD to extend the performance table ratings up to Jump/Manuever 6 for ships up to 2000 tons. This was in MgT1e High Guard pg43.

This system is for consideration. It is to keep the damage letter system in place and the damage from Book 2 weapons. It does not address the performance table or the Bk5 performance. I will have to think about that.

Instead because you are talking about HG ships, I suggest drives above Z are listed as 2W 3E, 4F or some system where if you have take 24 hits or go below nA, you drop a number. So a 2A drive takes a hit. It is now a 1Z or just a Z drive...


The progression for drives in CT '81 can be expressed as the following formulas...
Jump
Mass: Per Letter: 5 tons + 5 tons/per letter
Letters (or hit if you prefer) = (tonnage - 5)/5
Cost: MCr 10.0 per letter
Example: A Jump drive is 250 tons so takes 49 hits making it a 3A drive

Maneuver
Mass: 2 tons/per letter - 1 (yes that is a minus 1 there)
Letters (or hit if you prefer) = (tonnage +1)/2
Cost: MCr 4.0 per letter
Example: A Maneuver drive is 250 tons so takes 125 hits making it a 5E drive

Power
Mass: Per Letter: 1 tons + 3 tons/per letter
Letters (or hit if you prefer) = (tonnage - 1)/3
Cost: MCr 8.0 per letter
Example: A Power Plant is 250 tons so takes 83 hits making it a 4H drive
