Well i found this game called Dwarf Fortress, and i've seen it's world generator (it's epic!) and i see all these people creating maps by hand and using other programs, but what if you just used Dwarf Fortresses world generator to make maps? Their size depends on how you pick it and theirs even an advanced version of it's World Creator in the game that lets you customize it how you want. All you would have to do is, 1. Create the World 2. once the history is done ( i recommend the shortest history if you just want a map.) press the p key 3. go inside the Dwarf Fortress folder and head to the bottom. There should be a Bitmap/BMP file. Open it and theres your new world Here's 2 Large Worlds i was able to create, the second one i made in 5 minutes. Also i picked the highest size the generator could do. If you do plan on using Dwarf Fortress for your world creations i highly recommend you download the Lazy Newb Pack, because it comes with a graphics pack that actually makes it look like an actual world. Without it the world just looks like a big mess of symbols, numbers, and letters. (i used the Lazy Newb Pack for both of these) Watch out these are large (Move your mouse to reveal the content) Watch out these are large (open) Watch out these are large (close) Here's the download links for the Lazy Newb Pack, it installs dwarf fortress and the same Graphics Pack that i used all at the same time ^^ Windows: http://dffd.wimbli.com/file.php?id=7622 Mac: http://dffd.wimbli.com/file.php?id=7922 You will need something like Winrar or 7zip in order to extract them though. When you do just make a new folder, highlight all the files that show up in winrar/7zip, then just drag them over to the new folder you created and wallah, you're done^^.
