...I enjoy No Haul/Limited Haul worlds myself. i love them
When you find yourself in a good solid tribe like Hugh and I were in on W56 it gets really fun! OHYEAH was a tight knit group for the most part. Handfuls of months down the road we had core members that had to leave for various reasons which started us down the path of decay. you do realise i'm on 56 don't you ;-)
As for the OPs complaints of these types of worlds. Look at how you took XX and made it a powerhouse in the first place. You took from here and you took from there. All you did was gather the strongest people in the area for a time until real opposition presented itself. not quite, the majority had already left before impact 'redeclared' at which point we were already well and truely looking for somewhere else to go. We didn't crumble due to war but due to trusting the wrong people, but meh stuff happens, it's all a part of the game.
Look what you guys did to Invade. Not only did XX declare but also Censor and =D-N= declared as well. Once the leadership of Invade jumped ship the rest of the tribe crumbled. Then the bigger placers were scooped up by the powerful tribes and the smaller ones became food. Its a well known process by now.... i'm not sure what your point is here.
I remember at how tight knit OHYEAH was in w56. We took on tribes twice our size and caused them to disband. If you can find that loyalty in a tribe I suggest you stick with it till rimmed! Its a rare thing to find these days yes it is rare, i'm glad i found it in MoM
