I love Bungies Halo games and I'm pretty dissapointed. I knew it wasn't going to be like Halo but it really just feels like a worse Borderlands with some MMORPG stuff thrown in. Roaming around in Russia was decent but not very exciting. The first strike was just two huge bullet sponges that took forever to kill which was a big let down and I really didn't like the PVP.
It's a shame because when I first heard of Destiny I was very excited.
Edit: And they removed one of the most enjoyable things from Halo. The weapon variety.
