"The original Resistance: Fall of Man was released as a launch title for the PS3 back in November 2006 and it turned out to be the shining light for the PS3 at the time since there were only a handful of games available for the PS3 when it was released. The game went on to sell almost four million copies. The sequel, Resistance 2, released in November of 2008 and has sold over two million copies to date. Killzone 2 was supposed to be released right around the time that Resistance 2 was, but it was pushed back so Killzone 2 could be refined more. I didn't believe that then, and I don't believe that now. I think the real reason it was pushed back was because they realized that one game would take sales away from the other and they decided to separate the games by about six months so each could have their own release window. Now that both games have been released and they both are good games, how do both games compare and how can both games keep their own communities without stepping on each other toes?"
