See for me I don't purchase a game unless it has stellar multiplayer. The reason being that a game without it just lacks the replayability that I am looking for. The gameplay is what matters most to me in a shooter, sports, and fighter. I play RPG's and Adventure games for story first, and gameplay mechanics second. I play MMO's for gameplay and social aspects, and not the story in any way. I could give a damn what the lore behind a dungeon I'm exploring has, or a boss I'm killing.addeB said:"depth"? A very few multiplayer modes have a story, and with out a story, a game doesn't add depth to the game for me. For me multiplayer is just a little bonus that i can use if i get bored.
If a game doesn't have multiplayer it must have at least 80-100 hours of single player content for me to even think of purchasing it. Because frankly 80-100 hours is nothing compared to the 500+ hours I could easily invest in an amazing shooter.
The reason that shooters sell so well is because of the multiplayer experience, and not the story. It's not a coincidence that MW2 sold so damn well. It's not because it had some unbelievable single player campaign. It's because dozens of millions of people are addicts for the MP, just like they are for Halo, Gears of War, Counter Strike, Unreal, Quake, and all those other shooters that are MULTIPLAYER DRIVEN GAMES.
If the aforementioned games didn't have MP, guaranteed they wouldn't have sold even half as well. Maybe not even a quarter as well.
