What I would really like to see is a 1turn/week gunboat game.
I mean signing up for a no-quit game might entail 50 turns = 2 years of play. There is no way I could commit to that length of time.
While I realise that it would be twice as costly for the participants, there is in my opinion no reason to have 2 weeks go by since there is no communication between the players and that is what takes up the time in normal games.
“A 1turn/week I will not quit the first 15 turns” game would be ideal for me.
Perhaps I am just spoiled by having visited the F2F event where you can actually develop a nation in less than half a year.
Also I would limit the length of the game to 30 turns, not 50.
