Scratch

This is how it would go:

There would be a button saying start. When you click that, it asks you what your username is.

Once you answer, you enter into the Sci-Fi world of the MMO. You will go into a big world. At the top, there will be a button saying "Who's Online?" When you click that, it shows a list of people who are online.

Then, you can go back into the world and click chat. When you click that, you have to answer a question, saying: "Who do you want to Chat with?" If you enter a person's user name, and that person is not online, it says: "Whoops, looks like that person is not online, would you like to send a invite?" When you click that, and that person comes back online, they get a letter saying: "[username] has sent you an invite to chat, would like to start chatting?" Then the person would answer.

But let's say that the person was online, another questions would appear saying: "What would you like to say?" Then, when that person's receives that chat message, they can chat back and forth. You can also meet people places, like you can say "Would you like to meet in the market?" Then the person would reply.

If the person says yes, then you can go to the Market Place, and click Meet. Then you can enter the username of the person you are going to meet there. Then that person's icon would appear, and you can both buy stuff at the Market place.

If this is too complicated to make, you don't have to do it.

I would like to get more advanced people to help me on this, you must have experience with creating games (not in Scratch).

Thanks!
