Why did you get into FLOSS game development? It is one thing to get involved in the free software movement in general, it is another thing entirely to decide that this should apply to games, or that games are needed at all when you could work on more "useful" pieces of software.
I will start with myself. back in 2001 I got involved in Linux because I didn't like they way windows xp required product activation and deleted some of my files. I was already a player of Ultima Online, and I played it from 1997 - 2006 (both on unofficial and Origin/EA shards) I liked Ultima Online a lot, but I could see a lot of limitations with the client/server/gameplay etc that could not be fixed without really starting from a free software and free-cultural content base. So I began my idea of making a free software (not so much replacement as a better complete rewrite) of Ultima Online. I originally was going to go with Exult and replace the content, but then I knew I wanted Multi-player, so being lazy and not much of a programmer, I decided to look at existing free software multi-player online rpgs, I only knew of a few, and crossfire, although seriously lacking in many respects was the best of them at the time.
I took crossfire, and made another hard fork of it (the others being daimonin and atrinik, and some others as well) The lead programmer changed the tiles to be 45 degree isometric just like UO, much of the graphics got replaced, but for years and years it still had (and has, although it is much more fun now)some of the bad game mechanics left over from crossfire. Now I want to make it clear that Ultima Online is not the sole inspiration for the project. My other main sources of inspiration are things like the JRpgs, such as final fantasy 5 and 6, as well as some inspiration for the art style. The other inspiration for the art style comes from Heroes of Might and Magic 2, mostly as inspiration for the terrain tiles. Rougelikes are another source of inspiration. I love the random dungeon part that original crossfire already had, and I want to make it better. I also am inspired by that Ultima project that was sadly canned because they decided they didn't have the budget/interest for it. You were supposed to level up the eight virtues in a multi-player online environment. It sounded neat to me, and I plan to implement something like that in wograld.
