Best tip, find something that sells well and make it. Single items are best.
Get all 4 workers ASAP and join guilds to do so, or make an alt.
WARNING: you can not win this game without PAYING REAL MONEY, you will lose money constanty in the last area if you can't make things that you have to pay for.
-Start by making a lot of simple items...don't rush into the larger items.
-Keep in mind..leveling up workers means they cost more
-Keep in mind where you are located..does it make you susceptible to an attack/rummaging by another person?
-Guilds are nice..but so are guilds that help each other out. A guild with 30 members that don't help each other out may not be as pleasant as a guild with 10 members that constantly help each other
