Hello all, I have similar issues. I am unable to change the resolution of the game to full screen My desktop resolution is 1680x1050 but when I start the game in the video options> set resolution window there are no options.. it is empty.
Strange. You could try running NWCONFIG.EXE in the game folder to set the resolution.
Problems with the game not running fullscreen are probably a graphics card driver issue. You might need to make a custom resolution in the graphics control panel. I have a Nvidia card, and have to set the scaling mode to Aspect Ratio, perform scaling on GPU, and tick 'Override scaling mode set by games'. Without that last one the game runs with black bars around the edge.
