Professions-
What do you think about a sort of side quest feature for professions? One of TRPG's weaknesses is the absence of any real quests. Enter, Professions. We could add 'General stats' to the mod. It's your standard "strength, intelligence, agility, luck" sort of thing. But to raise these you'd take on a profession that raises a specific stat. The profession would require you to perform certain tasks to earn your rewards. I'm open to ideas on professions!
Reputation-
A reputation system would be cool to see implemented. This would work hand in hand with the bounty system, but be an improvement. The bounty system doesn't take into account attacks and kills: it only looks at stealing, pickpocketing, and mugging. It would be neat to track targeting and player attacks. If you often target players, attack them, and end up losing to them, your "Evil" reputation increases, but your "skill" reputation decreases! You would quickly become known as a "Dangerous Weakling" (Dangerous because you often attack first, Weakling because you often lose fights). By the same token, someone who rarely attacks first and only defends himself, but often wins the fight, could become known as an "Honorable Warmaster" or some such thing.
Reputation could neatly affect how town bots react to you, as well. Villains would not be welcome in towns and bots might refuse to talk to them (a percentage chance based on your villainy level when you #say hi). Merchants would sell you items, but the items might be more expensive. Villans could also rob merchants or bankers for small cash rewards (failing sends the town's sentries after the villain. If he's caught, he's jailed for a time. If his villainy level is high enough, he might be executed).
On the opposite end, "Heroes" would receive discounts at merchants and maybe a very small "good boy" interest rate on banked money.
