My vote for cargo and lifeboats... But it would be best to do this as optional mods and release later - MFM is WiP for a very long time...
By the way, the results give us 150% of votes. I wonder what mark do those IT masters had from maths in 5th class...
EDIT: They gave when just 3 people woted. Now they give about 200% ( just a guess... )
