I still do not understand why does it matter to you what people think about this game on this or any other forums. There were people who loved Duke Nukem Forever also and did not understand why everyone else hated it. If you like the game by all means enjoy it and just skip this forum all together but please don't try to convince people to have the same opinion about a game that you have.
Obviously there is no demo so everyone who is not sure about this game has to judge it by gameplay videos and reviews. For example Dishonored did not have a demo either, but most reviews and friends who bought it assured me it is a fun game, I watched some let's play vids and liked what I saw, so I got it, and I was not disappointed with it.
