What is the point of a good singleplayer mode? What should this singleplayer achieve? How should it involve the player?
These sorts of questions used to be the life and soul of the video game industry, but with the advent of multiplayer during the 16-bit era (the fourth generation of video games) the focus of development began to switch from solo play to multiplayer antics. At the time of the Super Nintendo's two-player function the second player was almost something of a gimmick in video games. It was an extra feature slotted in as an afterthought; the singleplayer was the meat and the multiplayer the seasoning.
