Reviews for Destiny seem to be all over the place. I've seen a lot of 9/10's and I've seen several 5 and 6/10's.
The thing about Destiny is, I don't feel it's a game that you can easily review right out of the gate. I think anybody who has been following the development of this game knows that this isn't going to be a self-contained, one and done release. Bungie has already stated that they project a 10 year commitment to this game. I look at it in much the same way as I do World of Warcraft. That game today is VERY different from the game that was released 10 years ago. I foresee Destiny being the same way. I fully expect to see additional planets, maps, story details, gameplay modes, etc added over time to futher expand and add depth to the game.
As for what the game is right now, I am having a blast with it. Yes it can be repetitive but what you do in the game is so much fun and the mechanics are so tight I honestly don't mind. I find myself going back to missions I've already completed over and over just because I love being immersed in the environments and find decapitating enemies with my pulse rifle so satisfying LOL! I'm just going to continue to enjoy this game for what it is right now and look forward to what Bungie has in store to make Destiny all they envision it to be.
