To be precise: we fought the battle of Ősi. This began on New Year's Eve 1944 and ended in the small hours of 1 January 1945. I got most of the details from Norbert Számvéber’s new book, "The Sword Behind the Shield", about Operations Konrad I, II, & III trying to relieve Budapest.
Rules-wise: a success. We comfortably finished the game despite it being a first time with the rules for most of the players, who were soon just using the QR sheet and needed minimal intervention from the referee. Obviously some gaps still, and some slightly clunky bits that need smoothing out. But definitely a fast playable game.
Scenario-wise: a bit rubbish, on two counts. The first is simply that this is really a straight attack-defence situation with very little for the defender to do. The Soviets have 3 infantry battalions with just one tiny SU-76 unit, facing initially two and eventually three German armoured Kampfgruppen. All the Soves can really do is hunker down in the towns and make it hard for the Panzers to winkle them out.
