If what you're looking for is resources, I'd suggest you try this one torrent called "Pandora's Box" for RPGXP
be warned though it's quite heavy, (around 4 gb) but when it comes to resources, it's got
-lots of tilesets.
-lots of character sheets.
-some bgm and ripped music to use.
-pre-edited to fit into RPGXP animations from some games
-panoramas.
etc... the list goes on
now moving on, yes it's true when you first open RPG-XP the resources available seem rather dull, but thanfully XP comes with the neat function to add your own,
if you check your menu in XP, there's a button next to the Database called "Materials" inside that tab everything is divided into folders each with different sections for
different resource materias, (such as battlers, field character sprites, battle animations, etc...)
basically inside of the Materials section you can import ANY image you want (I suggest you keep it as .png) into the corresponding folder, to make such resource
available for you to play with in RPGXP.
once you have all the resources uploaded on the materials section, you can head over to the database, locate your new content and modify/play with it until you
find what suits you best.
that's about it really,
