I guess I don't see Goblinization as a "fluff" tactic for players to get away with something. I see it as a way to allow players to choose what they want to play without being unduly penalized. Having characters Goblinized puts them on par with Humans (the baseline SR race) in terms of aging.
Joe... fast question... what puts humans on par with orcs or trolls in regards to attributes? Where do they go to spend 20BP and get a huge package deal on attributes and enhanced senses?
Why is it they can't enjoy their longer lifespan and more assets to buy cool toys like cyber to make up for those deficits.
Humans get +1 Edge. They get higher CHA and LOG than Orks, and higher AGI, CHA, INT, and LOG than Trolls. Plus much greater acceptance by the world at large.
Longer lifespan isn't referenced as a pro or con outside if flavor text. There are no rules for aging. In the huge majority of games, age is unlikely to have any impact beyond Roleplaying.
This is another MAJOR point. Goblinization is NOWHERE IN THE RULEBOOKS OF ANY EDITION OF SHADOWRUN. I felt the need to emphasize that. Anyone who does not enforce age is playing fast and loose with the rules as published.
Actually, Goblinization is mentioned all over the rules. On SR4A, 71 it specifically states that Goblinized metahumans are especially prone to early death. In terms of canon, SR4 trumps whatever novel you referenced citing otherwise.
That said, show me where the rules for aging are that people are playing fast and loose with? There are none. In all of the splatbooks, the revised SR4A rules, the whole ruleset, not a single rule on aging. Leonization is in a splatbook, making it only slightly better than a novel in terms of canon.
There are rules for far more trivial things - do you really believe this is merely an oversight? With major players like Bull and Fastjack who are getting along in years being so prominent? No...aging simply isn't fun.
You've asked for feedback, and as someone who has run games that have run across decades, let me give you mine.
This is a bad houserule. Sugar-coating it would do you a disservice. Rules that make the game less fun for your players need to be weighed very carefully, especially in a long-term game.
Aging is a great story hook, for the long term. It would be a really crappy mechanic, however. You want to penalize a player during CharGen for choosing a Goblinized backstory and potentially doing so well as to survive? No - people here are reacting negatively to this, and I would expect that to reflect in your players.
In any case, I really do want to get off this point. I'm far more interested in ways that people have managed to keep things from spiraling out of control without resorting to a complete and utter arms race. How they've managed to keep people from hyper specializing and making reasonably well rounded characters especially when karma seems scarce.
The only idea I've had along those lines is basically put up the carrot... karma will be generous so long as the characters stay well rounded.
Let them spend their points as they want. If they don't build a well-rounded team, start "hitting them where they ain't"...they should address their short-comings.
Characters will become more powerful. That is their reward. They will also gain a higher profile, allowing less room for error and more powerful enemies. If a high-power game isn't your end goal, you need to consider what you really want. Players want to improve their characters. Long-term games evolve. After a decade in-game, the PCs will be legendary heroes, or dead. Ultimately, you control the rate of advancement...but you can't, and shouldn't, try to slow it too much, or your players will rapidly lose interest.
