SitasOltremori Quick question for those that do play in Open sessions, what, if any, are there differences? (Other than possible PvP, which I have to admit I am not big on).
Solo is purely that, the same galaxy but no other real players.
Open is the same galaxy, but means you may encounter other CMDR's. Not all of them are friendly. You should try get confident 'knowing the drill' if you are interdicted / attacked, depending on what you're doing (you may be the attacker, who knows? ) - Plenty around here will offer advice on this.
Private Group offers a good blend of the two modes of Solo and Open, the same galaxy as everyone else but with controlled players within the group, typically like-minded CMDR's. This is usually a safer play for new starters as there is much less chance of you being interdicted.
