LuckCatchers

Embark on a grand and sweeping adventure in the skies with LuckCatchers, a free-to-play "social-economic sandbox RPG" from DiP Online. Construct your own settlements and exploit the land for profit, and hire on other players to work for you. Keep to the NPC-ruled cities or build your castle town from the ground up, and take to the skies with your personally designed airship in a world where you set your own rules.

There's no set class structure in LuckCatchers; choose your role based on what you want to do and the skills you have at your disposal. While there will be conflict, you can also use diplomatic and economic pressures to "persuade" your fellow adventurers, and in-game events promote a spirit of camaraderie and friendly competition. A reputation system helps keep the worst elements of society in check, though you'll never be completely safe -- or maybe you'll prefer to be the one with the bad reputation.
