I use Delphi 2009 (yup ObjectPascal dev alive here ), OpenOffice for the docs and calculations, UltraEdit for the xml, Lyx for the manual, a bit of photoshop and Maya + Mojoworld for the 3d. For the 3d dev i use mainly OpenGL.
For project updates i use a synch software + SVN/tortoise
when i need to compile C++ projects i use VS2010
I'm trying your game right now , 44.5mb wow.
Do you use only Delphi 2009 to write this game?
