Glad this popped up, I've been pulling out the classics lately, especially the older FPS games. Amazing what people have taken the time to update to run on new harder with minor tweaks for controls or games that still work as they are.
Playing Warcraft Orcs and Humans in dos box at the moment... it's so much harder than the later ones. Only 4 unit selection, no selection box and no hot keys! Madness!
