Currently a LOT of players accidentally make their first starship with a Wormhole P FTL Drive, and are then confused about why they can't return to their home system after going through a one way wormhole connection.
I suggest making the Wormhole PN FTL Drive the default/first, and then change Wormhole P FTL Drive into something else.
For example you could rename it to Wormhole P+ FTL Drive and make it cheaper to make and operate than the normal Wormhole PN FTL Drive. Or something like that.
Or simply remove the Wormhole P FTL Drive altogether.
