I would really like:
* More occupations and non-combat skills. Thief, trader or hunter is pretty limited, and I can think of a few more:
- Trapper/hunter (of animals, not humans): can kill animals like tigers and take their skins, or water ghosts and collect their shells or whatever, and sell them, either to a trader or sell them himself. Naturally a tiger pelt is worth a lot more in areas outside Jangan, where tigers are native. So travel longer = bigger profit but more danger. Basically a trader that has a speciality and can do things that other traders can't.
- Healer: like a herbalist; can kill animals and gather plants to prepare potions that he can sell to traders or adventurers. Perhaps he could also make poisons that thieves could buy and use...
- Perhaps even a farmer, who can sell his goods to trade caravans. Not sure how it would be implemented, but I think it would be a nice touch.
* Again, more non-combat skills, to make it more of a role-playing game than a hack-n-slash game that it basically is today.
- Barter: a high barter skill would let you sell your goods at a higher profit.
- and other skills
* More attributes. STR and INT feels a little limited. I would also like to see something like speed/agility that factors into your dodge/parry ratio, etc.
And if I venture into the more unrealistic areas, I'd like to see more politics in the game as well, to make it even more of a role- playing game/simulation.
Basically I want everything that would add more depth and another dimension to the game.
EDIT: Forgot a few important things:
- A stock market. Trade guilds should be able to sell stocks in their guilds. More stars and more successful trade runs = rising stock prices. It would add another dimension to the game.
- A banking system, where a guild/trader/adventurer can open up a bank and loan money to others, at an interest rate that he decides on. If the person fails to pay or just ignores it, gold will automatically be removed from his inventory or storage, and if he has no gold, he would either lose items to make up for the unpaid debt, or lose XP (like 1 gold in unpaid debt = loss of 1 XP or something)
Just a few thoughts.
