5000 resources isnt much. If we are talking about minerals? Some of the upgrades take only 1500 or so, but especially the ship upgrades are quite expensive. I got 50000 resources when I played the game thru and started over.

And 200k cash IIRC.
As for romances, I boned Miranda and that tattooe'd chick, Jack. Tho, it wasnt much of a romance with Jack, I told her I wanted sex and she gave me some, no strings attached.

The new blue chick wasnt that much into giving any, but then again, I was a bit put off when she told me she's over 1000yo.

Dont think you can have any with Tali.

I had dinner with the yeoman, Kelly, but that didnt go any farther than that.

*Note to self: Dont save her on the next playthrough* (And yes, I went all around the ship begging for pity-sex

)
.....
I wonder if you can cyber with EDI.
