BO2 at least introduces some new ideas into the franchise, whether we agree with them or not. The game probably got the score it deserves, not on par with the greats, not a terrible game, but a good game with replayability. It does have most of the same elements used in previous games, just rehashed into a different setting, but nothing too innovative.
H4 has NOTHING new to show. Halo is the same game it has been since the beginning. GS gushes over that game, with some game player called tsquare doing halo buttlove stories everywhere. Most hyped rehash of old ideas in years.
SAME enemies, SAME weapons, SAME environments, SAME vehicles, SAME characters, SAME story. BORING. Nothing critical said about halo anywhere on GS.
Seems like GS is getting paid alot of money to stay biased towards Halo above all others.
Honestly we already know Microsoft paid reviewers off to only give 9's or above (they have plenty of money to do it and it forces a lot of people to buy an Xbox). Just a few days ago they even claimed "It's the biggest U.S. entertainment launch of the year".
