1} Installs easily enough, the graphics were horribly slow before I thought to check the start menu folder and subsequently switching the rendering to OpenGL. Suggestion: Start the graphics mode selection when the game is ran for the first time.
2} Very slow mouse movement - even after ramping up mouse sensitivity, it's still only borderline acceptable. Suggestion: Bump up mouse/movement rate?
3} Low resolution. Possibly not changeable, but there are mods such as D2X-XL which do so. Suggestion: Integrate the hi-res mod as an option in the installer. May or may not be legally feasible, but bears looking into.
