Envolving game, deep, original... but easy, to easy.
I played it so many years ago and I learn to play it from my own, but I enjoy it anyway, i think i enjoyed it more than if had a guide. I had the same feeling the first time I played Civilization; just natural, just fun, just instrumental to play and progress.
This game needed more ambition.
May be its to late for a sequel. Nowadays game like eve-online, galactic civilization and others, are so much deep, ambitious and powerful in all their concepts. However a loved the three dimension map concept for battles, something that games like Homeworld just take it to their own benefit.
Its evolution baby.
