In 1996, I played a game on a Mac several times and loved it. I have been scouring the internet from time to time looking for it, with no luck.

It was a turn based space conquest game.

Not Master of Orion.

It was top down 2D with simple but clean graphics.

The space ships were triangles and you would launch ships at a planet to colonize it. Once you colonized a planet, you could set it to be high in production or science. Science let you develop more advanced ships. Once you had a more advanced ship, you could make it visit other planets to give them the ability to develop that level of ship.

This has been driving me nuts and if you could help, I would appreciate it!!
