So, I have been thinking about picking up X4. I know some Hexbear users have played it. My question is, what should I expect? Is it good? Do I need mods, or can I play vanilla? Should I get some of the expansions as well, or is the base game enough?

I'm not a stranger to complex games and working my way through them. I do play Paradox games, for example. I also play a lot of strategy games such as Civ and Total War (even on legendary difficulty). So, the game being complex doesn't really scare me, and I consider it a plus.

Just give me your two cents. It would be greatly appreciated. Even if you haven't played it much, any input would be welcome.
