I'm not sure if one like what i'm thinking of has been made, if it has please tell me.
I'm not a game developer myself but there is a program I would like to be created if anyone is up to the task.
Basically, its a chat box with some RPG features.
The RPG features would include stuff like a dice rolling system, being able to draw a map, upload and edit images(like character sheets),a simple level system (DM chooses when the player levels up and stuff) where the ability name is inserted and the level beside it, and the ability to manually write about a character (his/her stats and ability's and stuff, maybe only visible to the owner of the character and the DM).
Only the DM would have the ability to draw on the map.
And of course whatever stuff a chat box would normally have, name changing and commands and such.
This program would allow people to play Text RPGs online and have the freedom to use whatever rules they wish, which is what I have been looking for.
I'm really surprised there isn't one already.
