This is has been fun so far. We've made it through turn 4 of 20 and played about 3.5 hours. That may sound slow, but we had a couple of technical issues that turn about half an hour. Also, Tuna and I new to the game, so we're still learning and getting the hang of it, though turn 4 went quicker.
I think the one rule that needs to be looked at is the electronic warfare one. The card has come up four times, 3 against all three Warsaw Pact formations, and once against a NATO formation. This has really slowed things down since each hex that has an effected unit has to be checked each turn. It also means that the WP units haven't gotten to within two or three hexes of any objectives yet. I suggested that once it's used, that the card stays out of the deck for 2 or 3 turns. SDR suggested that it stays out until the targeted formation is no longer impacted.
