Ya Homeworld was awsome and I can only hope the best for it's sequal. I picked up Hegemonia though. It's a good game, but its very slow and sim-ish. Graphics are incredible but if you don't like the sim aspect...alot... its probably not going to hold you for long.
And as for generals, I like it mainly cause they went back to the old stuff. Example: a "Tank". Not a "Super Laser Energy Mobile Kill Platform." And it is balanced pretty well, every side has their little quirk that makes them good. If you really think its still unbalanced just wait, the glory of PC games is that you can patch em to hell.
