Rocks 2 Rockets, a Caveman 2 Cosmos mod-mod by God-Emperor. This is a trimmed down version of Caveman 2 Cosmos, aimed primarily at those who have difficulty running the full version. Current version: 0.4, which is v0 plus the 0.4 patch. (In-game, via the hover help you get from moving the cursor over your flag, it reports "Rocks2Rockets v0.4" and a couple of lines below that "Rocks2Rockets build 4" if it is patched to version 0.4 correctly.)

Patch Download: R2R Patch in the CFC Downloads Database (This is small enough to be here on CFC, where it is already available via this link. It is also available on ModDB.) I have run a test game on a system with 2GB of memory running 32-bit Windows XP without the 3GB switch and have gotten up into the Industrial era without difficulty. On a small map with the default 4 AI civilizations, marathon speed, no revolutions or civs spawning from barbarian cities, I had only 1 crash. That crash was at the end of the marathon first session on turn 595, playing straight through from the beginning of the game without exiting. That test game is now up to turn 1191 and still playable. I have also tested map sized up to Large on this system and a Large map is playable up over turn 100 (can't say if it will go very much farther than that, but it probably will). On a system with such low memory, you may not want to go over the Standard map size. Small might be the biggest size which can be used without issues past the Medieval era, although I am not sure of that. This is without activating the viewport feature. With the viewport active you may be able to play a size larger. The following post will explain what is in R2R, what has been removed, and what has been changed. Here is a very, very, brief summary: The content of the mod started as C2C's version 24 content. It has been trimmed. The DLL is the C2C version 26 DLL with later bug fixes and AI improvements applied. It therefore has the viewports feature (I have not really tested that though). I think the only post version 26 XML tag I have put in is the auto-build tag for buildings (it is not actually used for anything at the moment, but it should work - as far as I can recall, no tag from after v24 is used as the content is based on the v24 versions of everything). Update: As of patch 0.4 the DLL has bug fixes and optimizations up through revision 5148 plus the bugfix in 5208 (the intervening DLL revisions are not yet in), which is slightly past the revision number for C2C version 29.
