Is it really a "game" if there's no goal or "win" condition? Or is it a "webtoy" or "simulation" (or... "sandbox". Think it's a sandbox).
SimCity
I think the parent comment makes a good point that if you do define games as the mentioned, this and a few other things certainly doesn't necessarily fit with the definition. Still, games are often a fill-in word for many interactive things that use a computer.
