[Question] List of Completed RMXP's?

I am new here and am seeking a list of the completed RMXP's to play. Anyone know one?

Also (off topic noob question)- For Pokemon Nightmare, the RMXP, I can't figure out how to play it. I downloaded it and put the patch on and all I see is a .rgssad file which looks like it should be the .exe file. How do I start it?

Look through the threads found here in The Showcase.

As for Pokémon Nightmare, if you're having troubles setting it up / get any errors, you'll need to ask the game's creator in the game's thread (which I'm guessing, is this one?). The Pokémon Essentials category is for questions and comments concerning the starter kit for RPG Maker XP.
