I just joined, clicked Make a game and it directs me to this forum :@ All I want to do is make a game...
These forums are the best place to find resources for making games. I suggest looking down at the "Developer Resources" section of the forum.
You're going to have to open DreamMaker.exe either manually or from your BYOND Pager. File > Start Dream Maker or Ctrl + M

Then go to File > New Environment

This is the part where you name your project! And afterwards, just name your first .dm/coding file whatever you would like.

If you need to know how to do something, visit the Developer How-To Forum.

If you're having an issue with your code, visit the Code Problems Forum.

Thank you Kenny84.
