Nathan was obviously very knowledgeable in games that they have, but it was obvious that he probably just bought his accounts to play, as his skills weren't good at all, or he still plays just with his passion.
As for the others, it's obvious that they haven't spent much time playing games, as it's still very obvious that they're beginners and their characters mostly die because of common mistakes.
He could only probably enjoy playing with them after they played for a long time; but with their current circumstances where they had to prioritize their survival and were often training, he certainly couldn't play.
If he really got bored playing alone later, it would be better for him to just hire experts and pay them to play with him than to play with the people in their team, as there's no challenge in playing with them at all.
