Building is a main part of the game but it's not the only thing you do. Exploration is also a huge draw for lots of people. The whole world is randomized so you'll never see the same thing twice. You can literally walk for hours and see countless amazing landscapes. To top that off you also have gigantic caves to explore complete with pitch blackness(until you put up torches or find some lava) and that sense of isolation that people seem to love. So really if you don't care about building you don't have to bother with it. A simple shelter is more than enough to hold your gear and let you craft more.

I can't speak about Rogue since I've never played it but I don't see the connection to Civ.

I know about your issues with 3D but are you sure this would be a problem? You can play MC at at very slow pace if you want, no vertigo inducing camera movement and such. I think I remember you said you tried playing the Conan MMO? If so MC should be fine for you.
