Traveller5/ 2300AD homebrew

[Carcosa]

So I am starting to run a Traveller5 2300AD campaign. We are just starting character generation which I am using the 2300AD book as a guideline but switching over to the Traveller5 book for education and careers. I'm using the Traveller5 character sheets which could use some improvement.

I want to keep the skills and combat system from Traveller5 where you roll multiple dice (not just 2) to determine the outcome of an action. I'm trying to determine how a normal, difficult or formidable roll from Mongoose would transfer over into similar rolls in Travller5. Maybe add an extra dice to the roll for every 3 dm modifier in the Mongoose system?

Any suggestions on how to bring this together in a homebrew would be appreciated.

Normal Difficulty would most likely convert to T5 Average which is 2D, therefore the other difficulties would be higher or lower dice as appropriate, unfortunately i don't have Mongoose Traveller as i have always felt that MegaTraveller was the ultimate version of the system until now.

Note that the 5 labels used in the original 2300, and in MegaTraveller, and in TNE, are
Simple, Routine, Difficult, Formidable, and impossible; in 2300 and MT, those are 4 points apart.

THe Mongoose difficulties include 4 of those 5
Simple +6
Easy +4
Routine +2
Average +0
Difficult –2
Very Difficult –4
Formidable –6



The T5 labels are very similar, barring 2D and 5D+... but make a tight fit none-the-less
Easy (1D)
Average (2D)
Difficult (3D)
Formidable (4D)
Staggering (5D)
Hopeless (6D)
Impossible (7D)

So... a best fit by name is...

MT & T2300	MGT	T5
Simple 3+	Simple +6	Easy 1D
—	Easy +4	—
Routine 7+	Routine +2	Average 2D
—	Average +0	—
Difficult 11+	Difficult –2	Difficult 3D
—	V. Difficult –4	—
Formidable 15+	Formidable –6	Formidable 4D
Impossible 19+	(–10)	Staggering 5D

Notes: MT has an additional DM+1 on most tasks vs MGT; MGT a 7 stat is no mod, but in MT it's DM+1, so mathematically, the MT numbers work out to be pretty much the same probabilities for the average joe of skill X as the MGT numbers, albeit worked in a different manner.

The MT to T5 equivalencies are based upon the same discrete quanta... if you want to more closely match MGT levels, you could add a d3 for the missing steps.

Thanks a lot, that will help a ton. We just finished character creation today. So far so good!
