I might play. Though I'd vote for rules and accept being a minority. The game ran really smooth with a lot of rules with Stilldawn, Raglan, Carl von Dobln ect to moderate them.
What I write now is fact, what killed the game was the first restart, it made the rules more simple, and it killed a lot of the things that people had worked for in the game, that they had achieved, like using months and time on a castle and equipment to that castle or worked their way through the Ranks in the rules, Peasent to Duke, what a Journey! This may just be ingame fluff, but it was things to work for. And that was worth protecting. RPs to build these things that they bought for their virtual weekly income sometimes took and gave months and weeks of Roleplay.
It's just a few examples, though I think them to be good ones, the rules really made people more engaged. Whenever you make a game, computer or board game or like this you have to have many small goals to reach, in GSTK a "side-quest" was that to build strong relations, or use a bunch of Gold on a Castle which can help you in other goals too. All small goals along the path to the grand one, Kingship... And you didn't have to take and achieve all these small goals but they were there to do.
