Ask HN: Does a basic game engine prototyping tool exist, for common game types?

There are a lot of classic game engines out there (Real Time Strategy, Turn Based, etc), of which you can find countless variations. All of them have a basic starting point which involves units, buildings that produce units, unit/building parameters like health, damage, etc, a map canvas. These can be simulated at a very basic level, no graphics, no animations.

I want to build a Tower Defense type of game, and it would be great if i could build a very basic prototype just to simulate parameters like health, damage, speed, range, etc.

Does such a tool exist?
