Take a look at list of peoples which were working on deadspace 3 around 2 years to make game complete.
Dead space 3 arent so complicated, there are no quests, pvp, balance just simple fps game.
I am not trying here to talk with retarded Zackynuup because i usually dont argue with idiots. I am trying to show to the peoples who will read this and have no idea how hard making game is how it looks like. Dont listen retards such Zuckynuup who didnt archieve anything and trying to be smartest in matter that he did not even touched.
Sience i am one of not many real developers here (even i am only a hobbyst) i would say that from my own expirience an example that it took me 2 days to redesign fortress war hammer and make 3 levels of it and match it to game atmosphere. Thats just a fucking hammer what about the rest? think about it.
