I’m fairly confident I got the skills to do it, well I need to learn about databases that’s the thing I know least about.
I’m thinking of creating an online world where you can build a house, and your house can be found in the world and visited by anyone who plays the game (doesn’t matter which server you are on, you can see all player’s houses). First you have to buy a plot of land, then you can build your house. You can sell it any time you want for in game gold.
