Played this for a few hours last night and in that time died about 15 times... Mostly to the nasty little spitter ***** and the occasional Raptor...although I did punch a raptor to death at one point.
It was also difficult playing when there was one guy in our TS who was just sitting there listening to what we were doing, Popping out of no where and killing us repeatedly (He is level 15 and been playing all day) His response was "Its a pvp survival game...tough luck" ....While I agree, killing a lvl 4 for the 10 thatch he has and just "because" cannot exactly be rewarding.
There also seems to be an issue that Dinosaurs can walk through building wallls...or at least I woke up in our shared house this morning only to be eaten alive by the dinosaurs that had some how gotten inside the building without knocking the walls down or opening the doors.
That's the same for all games that have a pvp element, there is no unwritten code of ethics for the most part pvp is just as you describe idiots who are obviously much higher level or have better equipment picking off people who have no real intention of taking part in pvp pretty sad but will ALWAYS be a part of games.
This is one game I think i prefer watching be played than actually playing myself.
