SoaSE
Has a minimum resolution of 1024x768, while the netbook standard resolution is 1024x600, so some elements won't display (notably at the game start menu). There's all kinds of complaints on the sins forums about it, but as I haven't been watching those discussions, I'm unaware of any kind of workaround.
I suspect those games will slow my system down too far to play with a large galaxy size or with any of the high end options selected.
With GC2, so long as you have RAM, you're okay-to a point. A large all abundant should be doable, but a huge or gigantic is probably out of the question. SoaSE is another animal entirely, but with minimal settings RAM again becomes (or rather, should become) the limit.
