Hi Nathan. I applaud your and Ferram's efforts into making this realistic. I really want to use all of those mods. So, I was wondering: how do you actually use and play them? I bought KSP, played it for about 1 hour, searched for and installed MechJeb, and played some more. Installed the NearFuture stuff and KSP Interstellar, landed on almost all landable bodies, did most of the science, etc. Weeks of fun! After that, I discovered Realism Overhaul. "COOL!" So I installed CKAN and checked it. Install as advised. It added about 1 GB to my install with the smallest DDS textures, so the playtime between crashes dropped to less than five minutes. Hm. Ok, it took me a while to figure out what was causing the main memory usage increase. But after reinstalling and just checking FAR, Real Fuels and such, but not Realism Overhaul or Real Solar System, memory usage dropped with about a GB, and it became playable again. But then I discovered that FAR, Deadly Reentry and such are cool, but they disintegrate 90% of my realistic rockets. Ok, it's the joints, and you can disable it, but still. (And yes, Kerbal Joint Reinforcement is always installed.) They also spin and wobble out of control all the time. You have to go great lengths to design a rocket/lander especially for FAR/DR to be able to make them work at all. And NEAR is even worse. I mean, don't try to design and build a realistic one. That doesn't work. Use trial and error instead. Weird things might even "fix" it. Of course, all of that is made worse because MechJeb doesn't work anymore. I tried the NEAR/FAR plugins, multiple better gimbals (with the MJ plugins), etc. No go. Ok, I know there is Kos, and I might try and use that, but it would reduce my time to programming, instead of playing the game. Not that I played the game much the last week or so. I was busy getting it to work at all. I'm now back to mostly stock, which actually allows me to launch, control and land rockets, for about half an hour at a time. It's a shame, and I would really want KSP to be like you guys modded it, if only I could make it work. Ok, ok, if the Unity guys would finally fix 64-bit, it would all be much easier. Or if Squad had used an engine that can actually do it without having to revert to dirty hacks for just about anything. Etc. And I'm a programmer IRL, so if I cannot get it to work, who can? "It works for me!" is useless if you want others to use your stuff as well. How do you actually play this? It adds about 1 GB to a clean install, and reduces the playtime between crashes to less than five minutes.
