How about seting up a living room / personal room. And have to fly an obstacle course with a plane. I remember a game from waaaay back that had the basic Idea of that and I liked it. Flying obstacle course / bomb runs and so on.

I think I like that the most so far. However needs me to do quite some moddeling.. What do I need

Models (not going to do them in the beginning. Will use some placeholder models for now)
	plane
	(bunk) bed
	table
	bookshelf
	airstrip with small controll tower
	trucks and other toycars

Gameplay:
	arcade controls (mouse & keyboard / Controller?)
	start landed, have to take off
	to fill up on fuel:
		fly through random (?) placed checkpoints
		"bomb"-runs on 'convois'
	once all is complete, land for extra points
