It's the precise reason that why I read LPs. I'm interested in some plot points in JRPGs, but I sure as hell don't want to play those horrible things.
I vote Deus EX, System Shock 2, Grim Fandango, W40K DoW + WA (suprisingly low requarements - you can pull off maximum graphic with GeForce 2 32MB), Half-Life 1, Command and Conquer up to Generals, Impossible creatures, Fallout 1-2 and stuff.
