Going in, I didn't know anything besides the fact that it was going to be a shooter and it was made by the epic Bungie game studio. I did my best to stay away from news leaks and trailers. Once I got it... oh my lord, I couldn't stop playing.
It seemed to have so many hints at different games I've played in the past. Halo, of course, for it's shooterness and gameplay. Borderlands and Skyrim for the ridiculous exploration and jam packed full environment of respawning enemies and mini-missions available. There are also hints of Star Wars for little things like the speeder bike and overall feel of this sci-fi twist on fantasy. The world is huge and it's only going to get bigger. I'm so excited.
