@CWO:
One idea that you could pitch to the group prior to the start of the game, and making it clear that it’s entirely up to them whether they want to do so or not, would be to propose that your first game together be a training game rather than a real one. The game wouldn’t have a winner, and might not even be completed; moves and decisions would be discussed collectively as (or after) they’re made, and players might perhaps even have the option to “take back” a move they’ve just made that is an obvious mistake (though of course they could go ahead and play it anyway, and then see for themselves why it wasn’t such a good idea). If your group is comfortable with this, it would enable everyone to achieve a certain basic level of competence in a risk-free environment – with the goal being that when they eventually play a real game, they will be less likely to lose because of silly and obvious mistakes. If your group says “thanks but no thanks” to this idea, that’s fine too because it will implicitly mean that the players are willing to take ownership of any silly mistakes they do end up making; if anyone does end up losing due to such a silly mistake, they won’t be in (as much of) a position to complain that they blew the game in this manner.
This is how we play(ed). When just two of us started playing global, we often helped each other walk through ideas and options.
In fact, even now, just Sunday morning a reasonably experienced player was handling the Axis for the first time in ages. Once he decided he wanted to do a J1, I coached him on all his options, including his purchases.
For my partner on the Allied side, he had the Brits and Russia. During his turn I liked to help him see all his options and the consequences they might lead to. At first he thought I was telling him what to do, so I clarified I was just saying out loud what I usually do in my own head when I’m the Axis by myself. Helping him see the whole board and that I hoped he would do the same for me.
