Gyson seriously..do you understand marketing? getting sales going?
It is safe to include both options so all ranges of gamers know what they do. I have pointed it out twice now the difference between the two.. and you choose to ignore it.
What happens if someone is not connected to the internet? The way you want it they would be screwed..plain and simple. What I am reading is you just want it to be the multiplayer button and thats it.
I have typed it twice~ Singler player is one player only making the characters, guess what? Some players will be playing alone the entire game.. they bought it so they can play their way. Just because you think it makes them a "fool" does not mean you are right~ everyone plays their own way.
While you assume I cannot grasp your level of intelligence~ I regret to inform you I do understand what you type. To an experienced gamer one button would work for both (but then they have to make it multifunctional to detect if the player is connected to the internet or if another player is in the lobby area to make a character also). To a new gamer it could get confusing...
