First of all I wanna say that the gaming industry is developing really fast. Look at the graphics,the story line,the effects all are amazing.
Now about the Dark Souls II just hats off to NAMCO. I really mean that. This was the most amazing game I ever played. I worrked as a Game Tester for few months and played many amazing games and this one is one of my favs.
First of all what we all want in a game is a good story line and this game really fulfill that need. From starting to end the excitement never ends.
Secondly the graphics are amazing in the game. You can choose the costume,the build of your character,you can choose the character type.
Thirdly the enemies and the boss levels are not so easy and gonna challange your abilities. The enemy characters are really fantastic and feel like we fighting with something dangerous not like the other game in which it didn't feel like that the enemy is horifing. The boss characters are fantastic.
The chalanging thing is that you have to face the enemies every time you died and had to restart from save point which are very far away.
I didn't played the first part of the game,but I heard that that part is more chalanging than the second part.
