And yeah, conquest's ONLY similarity with solo is that you can only have one kingdom...that is only a small part of what solo was about. Without the 125 turn max, 3 turns per hour it isn't the same game with the strategies and difficulty of getting to the top and surviving there without any support in a living game. Conquest has none of that.
I don't mean to come off as elitist about the solo game, I just loved the gameplay involved in it for a solo player. It was a different game played differently. You couldn't play Chaos solo because even if you became king with a big lead (which I did a couple times) 20-30+ kingdoms would gang up on you to take you out. No matter how big and solid your defense is you would be countered with mass turns. It was just who had the most friends and a basic grasp of gameplay. Solo was about strategy. There were a lot of strategies to get to the top but pulling them off was another matter. You wouldn't lose to anything but being outplayed in strategy or beaten head on in a 1 on 1 fight (and with 125 turn max you could easily win a defensive war so it wasn't just who hit first, I won almost every single defensive war I had the last few ages I played it, because I built completely defensive).
My favorite use of the Chaos game was for a mini free for all game we played as the SOLO guild. I would put everyone who wanted to play into an app I wrote and it would randomize us some teams, we would each make 1 kingdom in chaos according to our teams at the same time and after a set build period we had a free for all brawl between the teams to the death.
But yeah, unfortunately we don't have the player base to keep solo going as a living game. It was always a fraction the players of guilds and even if everyone in guilds played it that probably wouldn't be enough
'cuz those are gonna be outsides!"
