We played "The War: Europe" from CompassGames almost every weekend from August 2023 til March 2024. At least 190 hours total. We decided to stop in the middle of the 2nd campaign mainly because there were a lot of rules ambiguities and holes. I think the Designer tried to make a "modern" A3R and failed (but tried to fix errors, and failed again) - The current ruleset is version 4.9 and still, it has soooo many holes. And the rules are written very badly. And the designer abandoned it - as he said, he "designed this game 10 years ago" and can't help with rules questions.
Apart from that there are about 160 rulechanging special cases only in a base game and they are tied to specific game turns (some are just one-shots, others work from turn 4 until turn 7, for example) - I can't imagine playing this game without spreadsheets. If anyone wants a copy with integrated addon in very good condition - I'm selling it (I'm in Germany) - all counters clipped with 2mm round clipper, map layed under a plexi for 6 months.
