I can understand that the radiation is there in order to prevent us from exploring into the island too quickly and probably requires the use of a radiation suit to get further in, but at the moment less than 1 quarter of the island seems to be radiation free, thus forcing everyone into one small area.
Now, in this small area I’ve found that the resources only seem to spawn in one concentrated area, which is where everyone is building, where all the “I MUST KILL EVERYONE!” people seem to hang out and where it just becomes impossible as you get killed when ever you venture out into this area to gather.
The animals are the same, they just seem to congregate in one giant herd in one certain area, making it impossible to gather food as all the window licker “I MUST KILL EVERYONE!” players seem to congregate in this area.
I did a little experiment today. I spawned and immediatly sprinted off for the edge of the radiation zone. On my way there I saw no animals, I saw no resource nodes except for trees (and farming from trees is a chore in itself). So I followed the very edge of the radiation zone, constantly having to alter my route to avoid other players (who would just start chasing me as soon as they saw me, but I would just run into the rad zone which would scare them off) until I came full circle back to the coast.
No resources were found, no animals were sighted and no radiated towns with zombies were found. Everyone just seems to be focused into one little corner of the map. So everyone is forced to kill and maim each other.
My suggestion would be to roll back the radiation zone a bit. Increase the number of towns dotted around and add more animals and resource nodes around the map.
