From what I can see it seems that collision programming for xsyon is a bear, and I really feel for you Jordi.
I also appreciate your breakdown of the percentage of players that are actually complaining... a very small minority.
Once done, I can see this as a huge leap forward for the new players, and we have 5 in our tribe just chomping at the bit to try their hand at building. Yes, a very few vets are complaining about what cannot be done with the new system, but seriously, do treehouses and overhanging ledges REALLY define the limits of what you as a skilled and creative veteran of xsyon can build?
tsk, tsk...
The reason that 3-4 people are complaining with hyperbole and disengenuous words, is not because it takes away creativity, but because it makes what they made by means of tricks and exploits no longer possible, thus their "creativity" will be seen for what it is.
I predict much more elaborate structures, much cleaner looking construction, and much better thought out layouts to the buildings people build. I predict there will be MORE building by MORE people than before, and that anyone will be able to create truely cool structures now, not just a handful of veteran players that are willing to resort to exploits.
Folks, using dirt and cantilevered supports and the new post supports, much of what you are complaining about will be not only possibe but much easier to build. And perhaps that what you really dont like. the fact that others will be able to build even cooler stuff than you did, and much quicker.
I will say in closing that if you are willing to leave this game because he shut down some exploits, then perhaps its time to look for another game. At least give it a chance to bear fruit before you chop down the tree.
