I agree with xmetatr0nix... I've always loved playing games, as you would watch a film, or read a book... Seeing characters and plotlines develop and draw you in because they're interesting and you enjoy that aspect of it. Rather than todays increasing emphasis on multiplayer gameplay.
Even in multiplayer games, I often prefer to play with NPCs instead, so I can have the oppertunity to wander around looking at the level (I'm a game designer, I get my kicks out of the game itself as well as the gameplay

), playing my own little stratergies (how many enemys can I kill a certain way etc), etc etc, without having to worry about "doing my part" of the teams efforts, or having to run through a co-op gameplay because the other player wants to get the goodies or finish it ASAP
More games like halflife, less like COD4 (However much I enjoyed the campaign, it felt like it was a token-singleplayer compared to the multiplayer)
