Hi and welcome to subsim
Well there are 2 ways to go
Either add a selection of mods to form your own install or add a supermod
There are 3 to choose from
WAC 2
NYGM 2.4
And GWX
Well I will have to stay unbiased and recommend GWX
New flotillas
New theatres of operation
New aircraft and shipping
I could go on
Read through the manual

Enjoy your stay
