Actually, the Marathon series has only 2.5 dimensions - the geometry is simply warped when one looks up or down. -Nobody 04:50, 29 December 2007 (CET)

I believe that the Marathon media for use with Aleph One isn't free, only freeware. Can anyone confirm? 83.252.26.221 14:52, 10 January 2008 (CET)

see [1], media's distributed for free but Bungie still retains the copyright.

It say that you can't sell them so this game have the possibility of being disqualified from this wiki. However it is unclear by what files they refer to as the source code are under the GPL.--Kiba 23:54, 21 January 2008 (CET)

Well technically, Aleph One is only the engine(under GPL) and not the complete game, the non-free data has to be downloaded seperately. Also I think there are some free fan-made scenarios also available [2] -- D'riss (talk) 00:04, 22 January 2008 (CET)
