*Wonders how the thread got on to the topic of storyline, shrugs, and posts*
I agree, but also I'd like to point out that before there were good graphics, games had to be "good." They had to have a plot that could carry itself and interesting characters, and they had to engage and interest the players. I don't think an FPS with classic style graphics (old) and some of the flimsy excuses they have for plots could do all that. In fact, I think what is most immersive about FPSs is probably the realistic representation of the idea that the player is using the weapon. Aside from that, all they really accomplish is the presence of threat and violence, two more things difficult to make seem realistic or more than humorous in the case of the first without modern graphics.
On a lighter note,
