Entertainment / Video Games / Alpha: Term used for a phase of development in the process of making an electronic game. Exact definition varies, but essentially it means 'most or all of the assets are implemented, and most or all of the functionality is implemented.' Anyone picking up an alpha game should certainly be able to get a very clear idea of the game's central idea and gameplay, but quite a bit of work remains to be done before the game is complete.
