Well.. I just watched the live gameplay and the maps look a lot cleaner visually along the lines of bo2 which is good...
Can't say how good it will actually play ,it being lan play..so that's iffy.
I'm used to boost jumps and jet packs now from playing Titanfall and Firefall (not related) and I like the vertical play,so that's a plus...
The similarities to other games mechanics is a non issue imo.. all games borrow from others ,otherwise there would be no fps at all after Doom or whatever was the first...
The Infinity Ward issue is also moot because the IW that made COd4 is actually the team that made Titanfall..and as rival said we shall have to see how Sledgehammer handles player feedback and development of the game post production..That and I like Treyarch games also so who knows , we can only hope Sledgehammer handles this better than the recent IW games(mw3/ghosts)
The dedicated private servers is the big factor for it to last any longer than a year as far as clans like us are concerned,I highly doubt they will let ppl run servers(like ours or Battlefield etc), eventually Blacks Ops had rentable servers but the gameplay sucked balls,so that's up in the air as well.
In conclusion..meh I'll get it and hope for the best.I say this because a lot of people hate on BO2 and i love that game so I have learned to come to my own conclusions..I just hope all the chatter amongst the interwebs doesn't kill the game before it's even played..
