I like the big updates, they give me tons of fun stuff to do, even though they take longer. The smaller ones were kinda "meh" sometimes. 0.19: Re-entry effects, that's nice, wheels for custom rover, still "nice". 0.20: New crew management, and new space center, which looks good. 0.17: A whole solar system to explore! IVAS! 0.18: Electiricty! New GUI! PROBES! New everything! Docking! 0.15: Hey planes, neat. But since I had C7 already it wasn't that much of a change for me. 0.16: EVAS, fun for doing things like... bowling.
