Greetings all.
Since BRP is IMO, the best gaming system out there, I would like to see how our BRP community goes about converting good ideas from other systems to the beloved BRP.
I would ask that if you post something pulled from somewhere else, please put who made it. Also, if you disagree with how someone else does it,
give your version and why you feel yours is better...simply saying "you're wrong" does nothing to further the hobby or your argument.
So, here are some that I found already on the forums. If there is already a thread with this topic, feel free to merge it friendly moderator

West End Games D6 to BRP by Wolverine (Nathan Baron)
I'm using the equipment straight out of the BRP book. One thing I must point out is, because Star Wars is very heroic, hit points are worked out using CON+SIZ as a total. BRP is a very gritty system, and can very horrific when it comes to personal combat. A critical and that's scratch one player character. That's why I doubled hit points for heroic characters. That includes major antagonists, such as Darth Vader, to represent the threat they pose. Non-heroic characters, such as Stormtroopers and the like, then keep hit points as normal. A blaster bolt should fell them easily.
I've decided that if you have 5D in a skill, a player simply adds +50% to the relevant skill base in BRP
For converting characteristics, here is an idea:
1D = 8
2D = 10
3D = 12
4D = 15
5D = 18
New = Original WEG
STR = Strength
DEX = Dexterity
CON = Strength
SIZ = Roll for using normal rules
INT = Knowledge + Technical divided by 2
POW = Perception + Technical divided by 2
APP = Perception + Knowledge divided by 2

GURPS to BRP by Aycorn (SIZ by Joseph Paul)
Okay, as requested.
Basically, it's like this =
ST = STR
DX = DEX
IQ = INT
HT = CON
APP = APP or CHA
WILL = could be translated to POW. Or not.
SIZ = Racial maximums for some of the BRP games was highest roll plus the # of dice rolled I believe, which would take a 3d6 human to 21. That makes a 2d6+6 trait top out at 20 then.
For SIZ you could consult some of the different weight to SIZ charts that were part of different BRP games. Jason has written that there is a SIZ chart included in the new one. Weight in GURPS does not seem to come into play all that much but there is a table for rolling it. You may need to wing SIZ for the spear carriers and NPCs though.
In Superworld weight over SIZ 20 is found by wt(kilos)=2^(SIZ/8)*25. This does not work below SIZ 20, does anyone know what was used for that? Anyone want to take a stab at rearanging that formula so that you can input SIZ and it will spit out mass?
That's really pretty much it. After that, just ignore GURPS ratings and plug in appropriate ones from BRP. If you understand BRP, that shouldn't be at all difficult.
Only potential tricky part is that GURPS allows well over 18. You'd just have to make a decision - over 18? Or stop at 18?
All in all, GURPS > BRP should be a piece of cake.
D20 to BRP by me
Ability Scores
The same six ability scores used in D20 are used in BRP, with some additions. Strength, Dexterity, Constitution, Intelligence transfer directly over to BRP without modification. Charisma becomes Appearance. Education is equal to INT+WIS divided by 2. Power is equal to Wisdom.
For races that do not have a D20 corollary, use the following table to find their racial speed.
| Racial Mod | Speed (default 8 for humans) |
| 10’ round | 2 SPD |
| 15’ round | 4 SPD |
| 20’ round | 6 SPD |
| 25’ round | 8 SPD |
| 30’ round | 10 SPD |
| 35’ round | 12 SPD |
| 40’ round | 14 SPD |
| 45’ round | 16 SPD |
| 50’ round | 18 SPD |
| 55’ round | 20 SPD |
| 60’ round | 22 SPD |
| 65’ round | 24 SPD |
| 70’ round | 26 SPD |
Ability score modifiers and attribute checks
When converting from D20 to BRP, ability bonuses are lost. Make sure to remove ability bonuses from skills before converting.
Classes
BRP does not have classes, and class level is immaterial in conversion.
Skills
The difficulty of converting from D20 to BRP is that most of the skills used in D20 are very broad based. D20 skill ranks x 5% = BRP skill ratings
Spells should be counted as skills. The level + 1 of the Spell is the Power cost to cast. The % of the skill is determined as follows (Level of the caster – the level of the spell) x 5% equals the skill percentage.
Feats
Feats will translate into a skill or act as bonus for other skills or abilities or as situational modifiers.
Alignment
There is no alignment in BRP.
Damage
Use BRP equivalents for weapons. Magic damage remains unchanged (although due to the low hp of BRP, you may want to reduce magic damage by ½ or by ¼ depending on the GM’s discretion)
Hit Points
Determine as per BRP (SIZ + CON)/2
Armor Class
Use BRP equivalents, although magic weapons and armor should retain their bonuses (although instead of an AC bonus, it becomes an AV bonus)
Rules
The following rules are easily able to be shifted into BRP without any difficulty; Initiative, Actions per round, Injury and death, Movement and Position, Combat modifiers and Attacks of Opportunity.
Difficulty Class
To change a D20 Difficulty Class to a BRP difficulty modifier, multiply the DC by 2.
I know there is a Dark Heresy conversion somewhere on here and I am looking forward to any others people may have. I will dig out my palladium notes soon and post those.
