The only limitation I can see ever being on the game without people walking away in disgust is the one that’s already on the cards: the dates fpr each unit. I can see Early War and Late War tourneys, but since this is a historical game there’s no justification for taking out units. A Panzer IV removed from a tourney could only be done so in some lame “what if?” event.
Otherwise WotC gets a kick in the groin from every person who stuck through this game from the beginning and were loyal customers (if not prolific). I’ll hold 'em down, everyone else get in line. ;)
Naw, I don’t think they’d do that. This is a historical game. Magic is not.
