GM: ok lets start the adventure.

Player1: can i be female?

GM: Does this look like teh kitchen???

its hard to find players these days. And summore the books are quite expensive. The miniature also expensive.

Not really true. Wayang Kulit (and TV and cinema) are played according to a script. Whatever happens, things always follow the script. In role-playing, there is no script. There's a buncvh of people and a plot, whatver happens after that is up to them

Okay.

Paper version vs this version :

Paper version

No PC/Console Needed
Electricity Needed
Free (and multiplayer as well)
Total 360-degree, go anywhere, do anything freedom -- want to fish? you got it. Want to swim? you can do that too. Want to slap someone with a fish? done lol

This version

PC/Console Needed
Electricity Needed
Not free (and not necessarily multiplayer)
There are a lot of things you can't do.
In short, I can do this in a pen-and paper RPG :

(1) Go swimming

(2) catch a fish

(3) slap an NPC in the face with it.
Let's see you do that with your game
