Here are the mods that got 5 votes, and exactly why they are/aren't in the Succession.
System Density
---> more stuff to shoot at.
Playership drones
---> this is pretty much a given

new armors
---> We don't really have an *armors* extended yet....
Repair Droids
---> Our only defense against Ventari D:
HD stargates
---> pretty stargates

ICX overhaul
---> I want to test out this weapon.
mining Pack
---> fixed most of the major bugs, hopefully there aren't any more >.<
WE5
---> this is also pretty much a given

Paper Fleet
---> Don't want to get stuck in the last few systems without much needed paper fleet support. Too bad we don't have the Danu to compliment them though...
Bussard Reactors
---> Without Descendence giving us free fuel, we might use these more often now.
Utility Items
---> I don't want to spend time looting when we could be spending it shooting at ships

Visible Damage V2
---> Helps target damaged segments, what more can you ask?

I also chucked in two more mods:
FL Civillian Ship Pack
Reactors Extended 2
This is because we haven't really played with them yet and I was unprepared to put them in the poll. Since they're new we might as well give them the benefit of the doubt.
MODS THAT DID NOT MAKE THE CUT:
Uncharted
---> last succession there was was an issue with finding Heretic, and I still have yet to make a Heretic -> Elysium connection through code. I'll work on a method to 'divining' gates and we'll see if it gets into Succ 5.
Named ore
---> Mining Pack has a scanner and a looter so we don't really need named ore.
Mined Asteroids explode
---> Mining Pack covers our mining needs.
Cargo Summary
---> We don't really use it.
SM&M
---> WE5 covers most of our weapon needs.
Dra Corp
---> same as SM&M
orbital space station
---> This got accidentally blown up last playthrough and we got blacklisted from the CW. *Not* going to happen again.
Civillian Crafts
---> It's a graphical mod, so we don't really need it.
Cestus
---> we haven't bought this ship, like, ever. We won't even see it ingame since we don't have Civillian Crafts either.
Aeonic ships
---> same as Cestus.
SF Item graphics
---> another graphic mod cut from the succession. (no space)
Variety sounds
---> Overrides a lot of weapons, and I'm afraid it will conflict in some way.
Rogue Traders Guild
---> still in beta, and stocks illegal reactors for some reason o.o
Item Repair Framework
---> last succession we had tons of sables and I don't want to break my fingers again. We also have repair droids to do this for us.
