Ok you maybe tried the X4....aka X Rebirth wich is a total trash (but everyone knows abauth it).
Well here is a real X4 (with worse grafic):

Playing this mod for 2 weeks now and i just cant stop playing it! So addictive. (+ a good time spend while waiting for other space games to come out)
All you need is a patched X-3 teran conflict (no need for albion prelude expansion). However i recomend instaling this with no steam if posible due to steam updates breaking the mod. You also need a torent program to download the mod. (and you need to put 2 fixes into files after you complete instal--its all in the tread)
Here is a game guide:

Only 110 pages hehe.
The only problem i had was the new voice, but it can be disabled. (voice sector mod caused lag when combat and sound overlap when going to another sector)
Unlike the old game, you start in the new universe wich expands over time. There are also some storylines, but i know you need good boron rep or they wont work...and some XXX sector unlocked.
Here is a map:
