When I got my 360 and was introduced to XBL and being told of news relating to unreleased games I started expecting things from games that I'd heard from my friends about. A great example was Skyrim. I'd played Oblivion back in '07 and was still playing my PS2 then and I knew nothing of Oblivion and when I was introduced to it, it blew me away. The features, graphics, world and entertainment and surprise of finding out new features and quests. But when Skyrim was announced I watched the trailer, told and was told my by friends about it, read every article, downloaded every image into my memory and watched every video. When I played the game and had my first dragon fight I was like 'I know how this'll play out. I watched the E3 gameplay.' My enjoyment factor dimmed because I knew everything about the game before it was even released.
When I first played Fallout 3 I'd only known what I accidentally saw from a New Game Plus review and that was your in a post apocalyptic wasteland and your dad is a scientist. That's it. When I played it I wasn't expecting a free roam game, radio stations, soundtrack, story lines other than the setting and everything else and when I played it. I pulled 3 sick days in a row just to play Fallout 3. When New Vegas was announced I did basically the same thing that I did for Skyrim and when I played it I knew the story, characters, some quests, followers and soundtrack. It dimmed the experience.
Now this year I'm getting Halo 4, Dishonered and Borderlands 2. I know only little about Borderlands 2 and Dishonered and spoiled myself with Halo 4. From now on I'm only watching teaser trailers so I know of the games existence, release date and pre orders so I can get the bonuses from them. It's tempting not to read and watch articles, pictures and videos but I'm going good and it's building up the hype. At the moment, my brain is exploding of excitement from Borderlands 2.
Try and tell me when you followed this, you got more entertainment from the game you bought. Also, don't read reviews other than the ones that say don't buy this game before you read them. Reading a mediocre review of a game changes your opinion on the game as do good ones.
