Hello to everyone.
I assume that you already heard about RPG Maker, therefore I'm not going to describe it.
But, just in case, here is the wikipedia article about it :
http://en.wikipedia.org/wiki/RPG_MakerMy Game Creation softwareIt doesn't have a name yet, but I already love it.
It's a creation software based on RM. But when I say "based on", it's not only inspired by.
In fact, this software, entirely coded in ruby, is capable of reading data files from the 2000, 2003, and XP versions of RPG Maker.
And it has for purpose, to offer the same functionalities from all the versions together (including VX), also offering other features for users wishing to have a more professional use of it.
It's a huge project !Yes, but I divided it into 7 independant sub-projects.

And I also recruted 10 people to help me.

Some of those projects have been available since 6 months ago.
I'm going to list you the meaningful ones :
3D Physics engine
It is, as its name says, a module made to simulate physics in 3D for a game. Very basic, it's mainly purposed to manage heigths inside 2D games. Like in Alundra for example.
Example of Heights Handling in Alundra 1:

Interview and article on the Relite website
A first article on the project (french) :

GUI (Graphical User Interface)A set of windows and buttons, developed from the lowest level.
Has the avantage of being usable in every ruby game using common graphics librairies.

RMXP, RUDL, Rubygame compatible
Note: All the projects that I'm describing are using this GUI.
3D EditorIt's the first step of my new Game Creation software

Dailymotion video (6-months old) :
http://www.dailymotion.com/KingKadelfek/video/x5rjv2_factory-011-dition-3d-usine-en-foli_videogamesConcretly, it's allows you to add "heights" to a 2D game.
This way, a zelda-like game can have realistic moves.
You can jump on tables, push a rock, everything is handled by the physics engine.

On this house, you can climb on the roof, to pass through the window, etc...
DreaMakerIt's the program extracting data from RM games.
It can extract the whole dialogs from a game, in order to edit them for correction or translation.
It's also the program that can convert a map from rm2000 into a RMXP map.
A technologic jump, of several years, and a transition from C to ruby for the data.
DreaMaker is available here :
http://www.rpgrevolution.com/forums/index.php?showtopic=26497Game editor2nd version of the 3D editor. It aimed to directly implement the new versions of the 3D graphic engine, as the new version of the physics engine.

It's also the software that will evolve into my new Game creation software.
DonwloadI'll add the links of the working projects soon.
