I think it's pretty clear that .18 needs to be known as the optimization update. My rig is no slouch, and it lags a bit when loading the textures on planet/moon EVA's. And i specifically made this computer for gaming. I would honestly hate to see how this game reacts on a lesser built computer system. So, the ONLY two things i would think are "needed", for .18, are as follows: Code Optimization: This makes the game, not only far more stable, but also easier for players that do not own gaming rigs to further enjoy KSP. Finish out the Kerbol System: This gives more space in further updates to add new things, and not need to spend time on planets, and moons. --------------- Things that would be cool to have, but can honestly wait: 1. The beginnings of the Career mode, perhaps coupled with an easy way to mod such things: This would allow just about anyone to create missions, and whatnot, opening up a HUGE amount of things to do. 2. Official Rovers. There are an awful lot of easter eggs that most don't even bother with, as getting your landing perfect enough to be able to quickly get to them isn't a viable option. 3. With the Rovers, implement the very basic type of Docking. Simply put, a module that has a Lock/Unlock feature. When it's locked, anything attached to it is held in place. when unlocked, they are not. This would make for a very simple way to dock, and undock. When moving something back towards something that has been undocked, hitting the key that is set to lock, would reattach the parts together. This is my 50 cents worth.
