I find it has problems, and firther support is currently up in the air.
Ths hip models aren't that great either.
To be honest, I think it is a distant second to Galciv 2 and it's expansions.
However, it does deserve credit for it's galaxy size, scope, and interesting approach to the tech tree.
I just think you'd be better getting Galciv2 or sins of A solar Empire.
