Even though I never play multiplayer, I was really excited for Destiny, as I figured I could just ignore everyone, as the impression I got was that you explore alien cities and do missions for NPCs and bump into real people every now and again. However, this trailer has definitely put me off it and I doubt I'll buy it - maybe when it's really cheap.
I thought it was going to be an RPG sort of game - exploring cities and 'dungeons', doing quests etc., but this trailer looks like it's just a shoot 'em up and I'm disappointed. My first impression was great, but it seems this game is aimed at the masses and isn't trying to be innovative. I know it's made by Bungie and published by Activision, but the only way I could describe the way this looks is that it's a cross between COD and Halo, which is not a good thing. "From the creators of Halo and the company behind COD" - they got that right didn't they? All the trailer showed was a variety of maps and people (aliens) shooting each other, which is exactly the same as the majority of games nowadays. I could pick up COD or Halo or something like Star Wars Battlefront and it would be almost identical to that trailer.
I really think Bungie have struggled since letting go of the Halo franchise. They haven't really done much else to note and, going by this, it seems they can't forget the franchise that made them famous and move on to other things. Of course Activision wanted to create a COD like game, because they know that's what they majority of casual gamers like, but I would have liked them to have taken this down a more adventure style route. I could be proven wrong, but we'll see.
p.s. For an Xbox One game, the graphics don't look very good, either.
