I agree, it is more of a space RTS then a R4X or whatever they called it

Maybe even just some playmodes to add in. like everyone gets his own star system from start, every planet colonized, but no buildings build exept for 2 metal mines an 1 ir 2 crystal mines at your home planet. then you slowly have to upgrade each planet. ofcourse those would be the central planets!

Or a mode where you need to err, steal a flag or whatever

There are way more options that could be added in the multiplayer of Sins, even in the singleplayer. It just feels empty for me.
Don't get me wrong however, it is still a very good game! (wont be saying great, for me to call a game great is like... err. Dunno, but it is very hard for me to do that with a game, especially the later ones.
Hope there will be more stuff in upcoming patches insead for me to beg at my dad to order it online again!
(stupid european publishers!
