2 generations of a franchise, Homeworld 1 and Homeworld 2.
But unlike many games that render their ancestor obsolete, Homeworld 1 and Homeworld 2 play differently, have different ships and the tactics being used are not the same and so allow for a different gameplay.
That's why i always play skimirsh with both with great pleasures without feeling the first one as "too old", in fact it is always as great as the second game.
My favorites RTS. I wish if the Homeworld 3 really happen one day, it will walk in the path of those legends.
