Gameplay and the Gameworld: The Asteroid map will consist of 100 x 100 tiles. The map will wrap around on all sides, thus creating the effect of a continuous spherical surface. Terrain will include rock, mud, mountains, water, and ice. Display will be centered on the players position in a 2D, top down display. Players will interact with other players as well as buildings, tools, and resources.

Resources: Commodities which players can gather, produce, and process which will fulfill players’ needs and generate money. Types of resources include: Consumables which players need (e.g. Food, Water, Energy) Raw materials which players can sell or use to make other goods (e.g. Oil, Iron) Manufactured products which players can sell for a profit. (e.g. Chemicals, License Plates)

Buildings: Large, immobile stationary factories and machines, which players can own and use to gather, process, store, and trade resources (examples: Iron Mine, House, Shop, Chemical Factory)

Tools: Objects which the player may carry in inventory which give the player different abilities (usually finding and gathering resources) (examples: Shovel, Pick, Metal Detector, Stock Ticker, Radar)

Economics and the Shop: Goal of the game is to make enough money to escape from the asteroid Resource tree has multiple paths to fulfill needs and make profits, allowing players to create and exploit niche markets Every asteroid will have a shop which will buy/sell resources and tools, as well as sell ticket off the asteroid Prices of resources determined by a real time supply/demand model Consumable prices based solely on local supply/demand, exportable manufactured products based on external effects

Trading with Other Players: Barter between players a crucial part of the game; primary means of interaction between players Players can set their own values for goods, independent of store prices Accessing an adjacent player activates a pop up trading window Windows consist of three panels (inventory, player, other player’s offer) trades are confirmed with a checkbox by both players.

Intended Audience & Platforms Perihelion is targeted toward Boys, Ages Perihelion should also appeal or Girls, Ages Perihelion is Designed for Windows, but... It will be Portable to All Major Operating Systems

Technical issues The programming language used will be C++ We Will used the library SDL for two main reasons: –The game is 2D and SDL is easier to use than DirectX in Windows and Xlib or SVGAlib in Linux. –If we only use SDL features and standard C++ constructions we can get a lot of portability. SDL provides routines for: –Graphics –Input devices (keyboard, mouse and joystick) –Timers –Threads –Sound SDL works on Windows, Linux, BeOS, MacOS and MacOS X

Technical issues The project is hosted in Sourceforge ( Some of the advantages of using Sourceforge are the following: –Space for a website –CVS server –Mailing lists –Compilation farms –Everything is free! The only requisite for use sourceforge is giving your project a free license. We choose the GPL one.
