GURPS Conversions

[Aycorn]

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.

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.

How do you determine SIZ?

[Joseph Paul]

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?

I am more for the SIZ table in RQ3. Its a detailed good table and I have already used it on the fly several times. I mean who can calculate in the middle of a game wt(kilos)=2^(SIZ/8)*25? (a very "gurpsy" formula IMO)

Make a decision based on what you know. If there's information there that you can extrapolate from (you have some sense of how big/small the creature/person is), just choose what looks right and works for you. If there's no information - wing it!

I guess so. My question was in reference to the PCs, mostly. I am thinking about converting Dark Conspiracy, and I have been thinking about this myself. It's not as easy as Space 1889, for instance. I will probably scale the 1-10 stat scale to 1-6 and have them roll +2D6, just use 2D6+6 for SIZ. That is likely how I would do GURPS too (the SIZ, anyway). Critters, yes, guesstimation. GURPS is scaled differently, compared to BRP, I believe. A 12 ST is likely a lot stronger than a BRP STR 12, for instance. ST 18 in GURPS would likely be superhuman, right?

But it comes in handy when you want to know what SIZ the Sun is. 768 SIZ by the way. Move that.

I included the info to show that they weren't pulling it out of their ...hats. And that formula does not work for things smaller than SIZ 20. I was wondering if anybody knew one that did?

Knowing the elegant formulas that underlay BRP is kind of neat for me. Which is why I find the firearm info so jarring. I have read here: http://www.hyperbear.com/cthulhu/cth...say-baugh.html that BTRC did not include firearm info for CoC in Guns!Guns!Guns! because the numbers didn't jive well enough to do so.

Actually ST 18 is a circus strongman. ST 20 is still human but Olympic class athlete. So the two systems are not that far apart in conception. How they play may be another thing all together. Compare what they can do in each system to test the conversion.

No prob. I take two dozen elephants and consult the resistance table ....

I dont, and I am not sure if I really want to know.

Well I think that the problem of this BTRC. I read the blog you posted and I have to say that this Bruce Baugh seems to overestimate his own abilities as game designer. How can he dare to criticize BRP and CoC if his only questionable contributions to the hobby are some vampire (yuck) books, a D20 gamma world conversion (yuck) and Feng Shui (yuckyuck). Alone this unimpressive list of "rpg"-books he wrote is showing that the opinion about BRP of this guy should be not more interesting to a BRP player than that of Mary Poppins.

Nah, Joseph, not that interested in GURPS. It just looks harder to get the 18 in GURPS than in the SB5 form of BRP, and I was making a *casual* comment in relation to that. Not a big deal.

The question about over 18 in the conversion is what I had in mind, but if they scale that close maybe it wouldn't matter all that much. There is that damage chart in GURPS, though. How would that compare? Would the base damage with weapons not quickly outstrip the BRP damage bonus? That's more what I had in mind with the term 'superhuman'. Sorry if these are stupid questions, but I don't know GURPS well enough to have a good idea of how the factors would scale between games. Idol curiosity and making conversation, and trying to be sounding post for Aycorn...
