I didn't see any significant bugs for me to regret the purchasing of this game. Most of this is just bitc*ing and moaning on the forum for the sake of bitc*ing and moaning on the forums. Performance issues are mainly due to weak PC's that people are playing on. Mine is not so up-to-date too (dual core, 1000 RAM and Nvidia 6800), but I loved the game more than HL2 or Doom3. Disappearing bodies didn't happened so often for me, perhaps 10 out of 200 - 300 of those that I killed. Sometimes if you walk into the spot where they had disappered, they appear back. There is some lag, but mostly at the beggining, when you start playing the game. Afterwords, it worked fine for me. I never encountered closed trader's door, this is something very rare. First time I ever heard of that.

Failing task is not a bug. Sometimes you end up killing enemies in one particular area, which happens to be a task from someone (trader, Duty or Freedom guys). Than it tells you to go and get your reward. If you don't get it in 2 game days, the task is a failer. So, big freaking deal. They usually just give you money. Money is not even a problem in this game, just collect artifacts and sell them to anybody, and there is your cash.

Didn't see the rain triangles, but I wasn't really looking for those. Hardly an important issue. However, the thunder storm was awesome. All that thunder and lightning was so freaking intimidating! I thought I am gonna get electricuted, so I ran inside! :)

They are not making fun of you, that's for sure. They just tell jokes. F.e.: Mercs captured a Stalker and they want to get his cash and artifacts. They dip him head-down into a barrel of water and say: "Cash and artifacts, now"! They pull him out and he says: "No!". They do it again, but he still says no. So, they just keep doing in it. After a while Stalker get tired of this and says: "Either you dip me deeper or hold me under longer, cause the water is mercy, I can't see anything!"

So, far I have heard about 15 jokes. But they repeat them often. Sometimes they just talk about other stuff, it is never really related to your game progress. They just moan about the weather, lack of decent food and beer and always wonder what the hell are they doing here. All the information that is related to the game and is important to a player is translated. I think it is a great idea! It really creates the atmosphere of Chernobyl. If you are not Russian, you sure would feel like to be in another part of the world where no one speaks your language (well, besides New Jersey). It kind of feels like an American or German or Chinese stalker in Russia. They will speak English ONLY when it needs to be addressed to you. Brilliant.
