Pay people to say shit, do shit, collect shit, deliver shit, destroy shit, fix shit etc.
In Sindome things don't come to who can wait the longest and hoard more paychecks, but to who is willing to take risks and earn things, typically by taking them from someone else. Players who aren't fond of this playstyle will frequently see their gaming experience stagnated for a game like this. All in all, Sindome is only rewarding when you are creating roleplay for others because that will most likely reciprocate back to you and you will be involved in fun stuff. Don't think only think in terms of "how to win by achieving material wellbeing" because what is important is the means, not the goal. This is not to say you should forsake all your material goals: they are fine and actually keep plots moving around, but how do you want to get that full set of Xo3 armor? Saving paycheck after paycheck or scheming and plotting your way around it?
Really, it's just a way for you to stand out a bit more, it doesn't actually produce RP, and since most of the process of making them is NPC or GM based, it's not really creating much RP for other people to create them either.
Let's be real, when people say RP they mean interaction with other people. So any use of money that goes toward encouraging more interaction between more players is money well spent.
I'd regularly spend money for information, for simple jobs, and if I had excess money I'd pay out more than any reasonable person would, because paying more for things is a status symbol. It sends a message and it makes people want to do more business with you no matter what your politics are. They will begrudgingly do shit for you even if they hate your guts, and THAT is the essence of creating conflict. It always starts off as something small like that, and it builds, and all while this is going on, you're putting money in other people's hands to do stuff with and it's possible they're spending it to work against you, and that's good for them and it's good for you. You're basically funding your own rivalry and a return on your RP investment.
That's the role play people are talking about.
I do not agree that clothes, biomods, and things like that are a waste and offer nothing to RP. If these items enhance RP for that character, then they are worth the money. I regard these things as being no different from any of many other frivolous things available for players to purchase. Will they necessarily make a big splash on the RP scene? Probably not, but maybe it will in the life of that character and people they know. Often, we're told that we don't know the entire picture of what's going on. That is true about the lives of other players' characters.
I agree with Crooknose that people get their kicks in different ways. What you do not find to be worthwhile, another person may think is very fun and advances the image they want their character to have in RP. They may have broader reasons to work on image in terms of how they look and how many toys they own, too. It will vary by the character and who they are.
I think playing Sindome and only collecting paychecks is a big complaint. More so than doing things to make a lot of money and hoarding it.
Even an admin can't know the in-betweens, things that aren't posted like character's feelings, or thoughts that aren't written out much (even though there's a command for it). There's a lot of other things that feed into that, many which no one can see. Only the author themselves have the answer.
In this light, we can only judge ourselves.
