There I was the other day, on the World of Warships closed beta forums, browsing between builds at work. Since it was a day of the week ending with the letter 'y', someone was complaining about other players in the match being stupid, being trolls, not listening, not doing teamwork, spamming local chat, whatever.
Then, near the end of his post, he rants, "I swear to god, I cannot wait for Star Citizen. When the Persistent Universe finally launches, I am killing every single game installation I have."
Star Citizen is not the first persistent multiplayer universe game, hell its not even the first space version of such. Getting a random smattering of people to suddenly cooperate in a 15-20 minute game is near impossible with differing skill levels, experience, commitment, and attitude, not to mention the communication difficulties of different languages and no voice communications. Star Citizen is not going to magically fix teamwork issues, just like EVE Online, World of Warcraft, or any other MMO game ever did.
Star Citizen players are going to be in for a shock if they think their world will be any different.
