Free 2d action rpg software for linux

Sonic Action is the first SRB2 Town related game. Anywhere, instead of the standard story that you read everyday, this time the viewpoint is more orientated to Sonic.
But Im not saying that well not appear in the game, nothing of that kind. Im planning to get we appear in the game. So dont ask me about that.
The engine of Sonic Action is incredibly good: you can think that Sega made it. Thats because six months of developing can do wonderful things. And this is not developed using programs such as Game Maker, MFF or TGF, normally used for make fangames, its programmed in C++ with Allegro.
And is more: Tails92 will port the different versions of Sonic Action to other OS like Linux or FreeBSD (Sonic Action is orignally programmed for Windows).
The story is very original, as far as the fangames stories that I know.. But you can get more info in the Sonic Action sections (scroll down the menu).

- New levels: Badnik City and Eggman Base (the last is incomplete).

Freedroid RPG project is an extension/modification of the classical Freedroid engine into an RPG. The main differences to the classical version are as follows:
- The Tux is the main character of the rpg.
- The game uses isometric viewpoint and animated pre-rendered 3d character models for all characters inside the game.
- Dialogs and chatting with friendly droids and humans: Multiple-choice menus and voice samples (with subtitles for those without sound).
- There is an item and inventory system that is modeled after some popular standards of the industry
- An automap feature was added. (this is currently a bit unmaintained since part of the code needs to be re-written for proper OpenGL support in the automap display)
- Saving and loading of games.
- Shops to trade things and skills to learn.
- Controls are different: Mouse is the input method of choice.
- This is a graphically intense game. Therefore the archive size is comparably *huge* and not suitable for modem downloads with a dialup connection.
Enhancements:
- This version, mostly unchanged from -rc4, focuses on making the development for the game easier, exports some hardcoded data into files, makes the map editor a bit more usable, and has other major and minor tweaks.

Pluto Request Action Library allows you to create a client/server application, where client sends requests, server replies with responses and optional actions. Very object oriented, and takes only minutes to get going. Same library used for both server & client side.

How does it work?

The client creates "Requests" which it sends to the server. The server will process the request, set some return variables, and can optionally add "Actions" it wants the client to execute in response. An example is a cashiers computer (the client) sends the central credit card processing server a request to "process a credit card", the server responds with the authorization code and also includes an action "give customer a message" which causes a message to appear on the cashiers computer.
Both the client and server use the same library. Both create an instance of RA_Processor.

The only difference is the server calls "ReceiveRequest" and the client creates the actual requests, and calls RA_Processors "SendRequest".
To create a request, just create a class derived from RA_Request. Add some member variables for the request and variables for the response. Your request must be derived from SerializeClass--a base class that facilitates taking an object (a request in this case), serializing the variables into a binary block, and then on the other end reconstructing the class with all the data. The framework handles everything. You just add the data members.

In the above example, the request variables would probably be the credit card information and maybe the customer ID, and the response variables would be the authorization code. RA_Request has a pure virtual function "ProcessRequest" which will be called on the server to handle the request. Both the client and the server have the same Request/Action classes. When the client side passes a request to the RequestProcessor, the framework handles serializing all the request member variables, making the socket connection to the server and sending the request to the server.

On the server, the framework will create an instance of the request class and deserialize all the data and call the "ProcessRequest" member function. That is the only function the server needs to implement. From within ProcessRequest, the server needs to set the response variables. When ProcessRequest returns, the framework will serialize the response variables, send them back to the client, update the clients original request with the response, and execution will continue. Less than 10 lines of code are required to make it work, and the project includes a sample client/server application you can extend.
