Death By Surfeit was correct about the unwieldiness of the alternate Sex Tricks system I'd set up. I've revised it yet again, making two major changes:
1) No ability score requirements for any particular Tricks. Instead, the bonuses conferred by most Tricks are dependent on particular ability scores and serve to enhance the base mod. This makes a Trick play to a character's natural strengths.
For example, I've rewritten the Sexual Expertise trick so that instead of transferring a flat 5 points from a char's SP check to the partner's Arousal check, the number of points that can be transferred is 2x the char's INT mod. In that way, a slightly gifted character (INT 12) can give his partner a small but still meaningful Arousal check bonus of +2, while a really sharp cookie (INT 16) could give his partner a bonus up to +6.
There are still many low-level Tricks that are not ability score-dependent and could be learned by any ordinary person, even Commoners, which seems realistic to me.
2) The second change is that I've redistributed the Tricks into nine difficulty levels (rather than only five levels), a scheme which parallels the spell level table. A character must have ranks in SP equal to or greater than the difficulty level of a Sex Trick to learn that Trick; thus no Trick requires more than nine ranks in SP, which again seems reasonable to me. A concise list of Tricks by level follows:
Level 1: Kegel Flex, Foreplay, Pinch, Envision Better Lover, Pace Yourself, Easy to Read
Level 2: Muscular Control, Physique, Intense, Striptease, Enduring, Quick Study, Delay Orgasm, Talk Dirty
Level 3: Sexual Focus, Resist Fatigue, Greedy, Selfless, Sexpot
Level 4: Bondage, Maw Stuffing, Orifice Stuffing, Sexual Combination, Instant Withdrawal, Resist Pain, Multiple Orgasms, Species Focus
Level 5: Support Partner, Coordinated, Tireless, Disease Resistance, Sexual Expertise, Responsive, Lover Focus
Level 6: Contortionist, Quick Recovery, Teasing
Level 7: Tantric Lore, Impressive Repertoire, Persuasive
Level 8: Stunning Pleasure, Everywhere at Once, Adaptive
Level 9: Overwhelming Force, Male Multiple Orgasms
(Note that many of these Tricks have been slightly reworked since my previous post, and some of those that bear the same names as Tricks from the Guide are not exactly the same. For brevity's sake, I'm refraining from posting summaries of the Tricks' mechanics.)
I understand that this is probably not the direction in which GUCK development is going. (I do like the concept of different schools of expertise, each incorporating its own progression of related Tricks.) Feel free to ignore any or all of these suggestions; I post them merely in the event that someone might find something useful. What I don't want is to bog down progress with yet another voice saying, "hey, let's scrap everything and go in this other direction" -- so take whatever's good and junk the rest.
For my part, I especially like the inclusion of very low-level Tricks that are available to persons of average ability. In the real world, almost anyone can learn the Level 1 Tricks in the list above. Many of them serve to prolong the sexual experience, which to my mind was a slight weakness in the original mechanics -- unless a male character has a marvelous CON score or many ranks in Concentration, it's statistically improbable that he'll last more than four or five minutes in the act.
Anyway, these are just some additional thoughts. Keep it going, folks.
