Toted as one of the toughest games by game sellers and casual players. Demon Souls a game in which you can use the online function to get tips and various other things from other players including being able to watch and see how another person went about the same scenario you are in. Will be shutting down it's North American servers on May 31, 2012. ATLUS Games said that prior to the shut down of the servers, they will be holding two events next month for the game (May 1-15 and May 16-31). ATLUS also has been encouraging players of the game to sign in on May 31st to say their final goodbye to the online portion of Demon Souls. The single player portion will remain unaffected.
Having never played the game myself I am not really effected as much as hardcore players of the game. I did follow it with interest but I just never had the time to sit down and play it. A few of my friends who played Demon Souls enjoyed the Online Style of play and the story behind it. When I gave them the news they were shocked but ultimately said it was about time the game has been going on for a few years and it was time to say goodbye.
If you are a fan of the game by all means you can play it online until 11:59pm May 31, 2012. But after that expect not to be able to connect to their servers in North America.
