Zoo Race cost about $7000 to make it overall, so it is possible to make something low budget.

You have to depend on your unique "ideas" and not on money like the big game companies do.

But, after your game release, then just be prepared for the hordes of "whiners" who wanted you to spend more money on it. hahahaha!
