Well i've made it quite clear about my views of the game, i haven't said its bad or good because i haven't played it yet. But the reaction to it is clearly over the top for whatever reason, there's been bad games before and they didn't get this reaction.
The reaction is "over the top" because this was supposed to be one of the year's best games. It was heavily anticipated and marketed.
If Sega releases a bad game (Yakuza: Dead Souls) nobody really cares because nobody knew it existed. But when a game that's actually hyped and marketed is BAD, then yeah, there's a huge shitstorm. It seems unusual because we're Sega fans and Sega rarely markets their games.
But when people are anticipating and expecting your game, you have to DELIVER. Nobody told Sega, apparently. A great commercial will only go so far if your game blows.
In this industry bad games are not usually graced with multi-million dollar marketing campaigns. A bad game from Activision (007 Legends) will be quietly released, not showered with a marketing campaign reminiscent of Black Ops II. Again, nobody told Sega this.
