There are tons of great mods out there but if anybody else is like me, they don't like to mix parts from different parts packs. That's why I've started thinking it's about time we had different "flavors" - complete parts packs that provide an alternative to the vanilla parts. These wouldn't be just some engines, fuel tanks, and decouplers. No, these would cover all the bases - aviation, space station modules, probe instruments - and then some, in addition to being high quality, balanced parts.
Currently, I think KW Rockets is closest to this goal, although they have a long way to go. Their parts all look good and work well, and they're balanced too. However, there are no command pods, plane parts, or utility/scientific parts.
I know ultimately it's up to the independent mod developers, but what do you guys think about an effort to provide complete, alternative KSP experiences?
