What is the one mod you couldn't play KSP without?

[mikegarrison]

I play with different sets of mods just to see what it is like. But there are a few that I feel are must-haves to make the game fun.

• MechJeb
• Nertea's mods (opens up so many more options for ship design)
• KAS/KIS (gotta have something to do besides plant flags)
• KJR
• Chatterer
• KAC (not needed early on, but essential later)
• RealChute (so much better than guessing how many chutes to spam onto a ship)

+1 for KER. Not only is KSP virtually unplayable for matters of deltaV but also the very significant matters of:

• Thrust torque across stages and altitudes in atmosphere.
• Timing suicide burns.

I could - but I only let myself use mods for stuff like this. I wont let myself change the science difficulty settings in any direction other than down.

Or you could land on Duna and  Eve , not to hard and the science is in the buckets. Also an orbital science station provides molto scientia.

For me MechJeb and Nertea's mods are essential.

Karbonite.   It's been a mainstay since before ore mining and conversion was a thing.   I just prefer the system, and now I'm fooling around with Karborundum engines for endgame ships, they're a blast.

Close behind would be tweakscale.
