I tried the shorter games when I started, then a long game having decided I like it. I soon found the easy games far too easy and actually didn't teach me much about the long game methods and tactics.
This one, with double the Pax numbers in a time scale where the big 4 prop aircraft work well, and so few players. it's not going to be a learning curve, more of a leisure game, just for fun. Enjoy, but not for me. At the moment. I do remember Sami saying these easy games were for new players, requesting the big players don't dominate them. Mmm.
