in the end of the game it looks like there is nothing to do just going to the TG - Trading items and making more zulie,,
so I think you should add new features to the game such as:
- gathering skills:
that will be used to gather materials from all over the world starting from level 1 which will be used for selling or to be used for an artisian
such skills as ( mining - herbalism - fishing - woodcutting )
-housing system:
make a space that is private for every character and he will have the ability to put furniture, designs etc..
-Acheivment system:
It will be a good way to waste the time and show other people your in game progress.
i cant think about anything more than that, but atleast give us something to do at the end of the game, think about how to make it better.
