Regarding Shareware:

Currently, the binary is in a gratis-free form. This is a result of the project currently being an alpha release and the binary is simply something for people to test and preview. That's really all anyone can do with the state that the game is at.

As far as the open source nature, yes, the source code will always be distributable and able to be applied to any project. This is because eventually this project will split into two forms: 1) the engine, 2) the actual game. As development stands, the current alpha version is essentially the engine. Eventually, this project will fork and the actual "game" will simply be cruft sitting on top of the engine, while the engine will remain open source.

However, the cruft on top of the game will not be open source. The cruft on top will take the form of data (mostly), some glue code, and other miscellaneous code that is not essential to the engine and only particular to the game.

As the project forks, the nature of what is open source and what is closed source will become clearer. Right now, there is only one page for both things (since it is early in development), so the distinction isn't clear cut at the moment. Currently, all source that has been put into version control is open.

When the project is mature and in a "finished state", I will release a demo version of the game and a fuller version that includes everything for a negligible fee (about the price of a cheap iPhone app). And, because of the open/closed source distinction is conflated with gratis/fee, baldly saying something is 'open source' (without qualifying what is meant) to many people implies categorically that it is or will be free of charge or fee.

So, I'm reinstating the Shareware designation.

Sorry for the misunderstanding. I thought the game and the data were under the same license; and something can't be shareware and open source at the same time (people would just edit the source to remove the restriction). I highly appreciate your decision to release the engine in this manner. --Linlem 22:15, 23 December 2010 (UTC)
"Open source" as defined by the OSI refers to free (as in libre), meaning freedom to view, modify source code, and/or redistribute. The definition does not mean free, as in free from charge. So, as a general definition, software can be shareware and open source. Paid software and open source are not necessarily mutually exclusive, as many people believe.

For example, GPLv3 licenses explicitly state, "You may charge any price or no price for each copy that you convey...". Another example are BSD lisences, which are compatible with proprietary lisences. BSD lisenced code can be incorporated into for-profit or not-for-profit code without restriction.

However, different lisences have different provisions for different things.

The reason I am putting some code under proprietary lisence is not because I want to charge for a version of the software -- I could charge either under an open source lisence or closed source lisence. I chose a proprietary lisence for a portion of the code as a technical limitation. If someone is going to copy the closed source portion of the code, they will have to reverse engineer or make their own version from scratch.
