I've recently found, and re-installed Freelancer.. and i cannot wait to start back up.
I'm hoping that with this mod i can play the base game solo? Correct me if i'm wrong, and then come online.
I used to play a very long time ago, so it's going to take me a while to figure everything out.
Hopefully I can get the right settings for the game!
As far as setting up accounts, look into the Veteran Package scheme. That will start you off with some credits, some ships and a quick booster to get you going.
On setting up new accounts, right click in the "Accounts" section of the launcher, and create a new account with a name, description and category that you can remember it with.
If you haven't already, it would also be worth joining the new official Discord as well, so that you can get direct help from members of the community.
