one of the Youtubers i watch did a WotC modded psudo-longwar campaign with most of the mods getting rid of ruler reaction and a few of the more BS "mechanics" they seem to like putting in.

On his fourth mission (which happened to be a VERY critical mission) they gave him the Viper King.... his highest HP soldier had 5 hp.... Long story short he had to EVAC losing the guy who spotted said Viper Dickbag, and due to not completing the mission he had to scrub that playthrough.

Total run time... Just shy of 2 hours..

Best part, it was that first "critical" mission that they damn near GIVE you a freebie win for plot reasons.
