Ok, then see Horizons as an example of an MMORPG with heavy options for major non-combat projects. There are others with at least an attempt to do such things, too. Text-based MUSH games are often heavy on non-combat elements.
There are some non-commercial VR games which involve players building worlds.
For commercial non-violent Online strategy games, you may be describing a little-explored niche. Not sure. Maybe you can pitch Barbie World On-Line to Mattel...
I think the commercial Online strategy market is pretty stuck on RTS, and that genre has so many time warps and low-attention-span types of activities already, I'm not sure how it could work well without the violence. "Construction rush! I'm gonna buy up all the undeveloped land so I can start my super mall before my opponents!"
Mainly teasing, there. Do you have the germ of an interesting game in mind?
