You have ipad/iphone in platforms section. I cant find game on AppStore

unity3d Unity3d.com
unreal engine Unrealengine.com
cryengine Crydev.net

First one is most simple, IMHO. There are many tutorials and open source prjects around internet.

Separation modules to make some stages?

ooohh. Roborts tools sounds good) Give me time machine to get complete game.
So, realy, physics sanbox with scripting is my dream. I used secondlife but its restrictions kill any ideas. I tried unity3d too but didnt find working idea how to add scripting in unity project. so, maybe you have any expirence in this part, links to read?

Very cool project. Good replacement for sketchy physics, but partialy )).

If you will add any scripting language it will give opportunity to create any gameplay from car battles to mars exploration simulation.

Loading custom maps from heightmaps and texture files (optionaly normal and specullar maps) would be great too. Or add please moon and mars maps ))

And about bugs: it's very hard to bind suitable control keys to parts because some keys (like "Q" "E" etc) are using as interface to add/remove parts
