I played FB18, Red Banner Days, which is one of a couple of Festung Budapest scenarios that were published in journals. This is a pretty fun one: the Russians attack first, needing to overwhelm a small picket force of Hungarians, then dig in as a strong German force counterattacks them.
Lots of stuff to do for both sides: Germans and Russians each have toy-toting infantry and a bunch of armor, and the Russians have some towed guns, although obviously the towed guns never did anything useful because towed guns have never once had an impact on a scenario in the history of ASL. I'm not sure why designers keep adding them to scenarios.
On the last half-turn, my German opponent hit his CVP cap with a boxcars during the rally phase and the Russians won the game. My opponent predicted the 12 before he rolled it, but felt he was far enough behind he needed every body to try to push the Russians back out of the victory buildings. Pretty fun--the Russian did a lot of street fighting and went 3-3 or 4-4, which probably swung the game, as it's going to be pretty difficult for him to bring down the German Panthers any other way. I recommend making sure that you play this one the next time you break out your Festung Budapest scenarios.
