not so sure i should revive this thread, but I\'ll just drop my 2 cents anyway, who knows what sequence of events it may start? 8o)
regarding \"acrobatic\" habilities, I believe it could become important part of getting into the reality fo the ps universe, you don\'t want peopleto go where killroy was? if you don\'t want to use creativity, just place a few more of those irritant (to me, but I actually really don\'t mind, I just wishsome other solution was used) invisible walls, we shouldn\'t be able to go over the wall but around it? just let the birds hit the big glass window, we don\'t even know what exactly is this place we live, and we don\'t know how the gods powerfull reallity warping dimension bending powers works, what one more lame invisible war is compared to some really big misteries in iliakum, hell even irl we are not sure if that damn cat in the box is alive or dead. Of course with a little of creativity, a deadly tentacled flesh eating poyson ivy is growing around the castle tower, or a \"misterious\" reflection is in place over the maze in the dungeon, if you try to jump you hit your own reflected head, or just the mountain terrain won\'t let you alive, you reach the chimnee of the main room of the \"misterious\" mage that live in the center of the mountain, but the tiny vibrations of your breathing resonated with the cristal structure on the nearby cliff which released some of the acumulated solidified fumes from the mages years of alchimy, whic happens to fall over you killing you, pure pavlovian training of the players. Of course there will always be the ones with screenshots of the famous m0u0m boy over the edge grafitti, hopefuly there will be formed a guild of those (virtual)reality hackers*1 , with a spirit of a grey/white hat hacker, find how brake in, tell and show everybody they actually did it but only share the actual means of it with the devs, just applay real life logic to the project and the same proven successful methods will aply just fine, as when it comes to basic concepts it is actually the same thing.
as for what kinds of \"acrobatic\" habilities should the inhabitants of yiliakum would have, I would sugest watching a couple of displays of habilities traceurs (praticants of Parkour*2) have developed, firstly scale them a bit up for the top lvl anyone would reach (after all this is fantasy, also I am not sure of the intensity of the gravitational field, or similar force, in yiliakum, take that in consideration too) after the absloute top yiliakum human traceur capabilities is defined, scaled them acordingly to each races constitution and diferentiated features (perhaps the tendons in the enki are more elastic, and they might also have muscular fiber with some similarities with crickets and fleas jump muscles, but of course not going too much over the scaled feline( /primate) muscles capabilities. krans go up heavy, and come down hard, but their phisiology is already somewhat fitted to handle it constitution, if they don\'t feel them selves as heavy, their legs can go up with similar easyness as a human would lift his own, them I believe probably one of the few diferentials is that if he runs it would take more external energy to stop him than to do the same with a aeroboned klyro.
Just picture this simple (theoretical) experiment there is this two \"canons\" one made for firing a cubic meter of steel at 10 km/h and another one build to do the same thing to a cubic meter of styrofoam(r), both of them fire at the same time, both \"projectiles\" exit at the same speed, side by side, they move the same distance, but in front of which one of the two would you park your car?
damn, have to stop writing this mockup real world phisics applied to vitual reallity essay thingmabob, got do something else right now, perhaps later I\'ll add something I probably missed for now 8o)
sorry to bother yall with all this pseudo phisics and redundant rewriting of the smae idea or something like that 8o)
