Bit-tech is running a feature examining the progress PC games have made over the past couple decades. The article highlights aspects of modern games we often take for granted or nitpick, and compares them to earlier games in which such features were implemented poorly or not at all. Quoting:
"Doom's legacy is still being felt today in fact and it's a fair bet that you can take any shooter off a shelf, from America’s Army to Zeno Clash, examine it, and list a dozen things that those games owe to Doom. Things like the wobble of the guns and the on-screen feedback that tells you which direction you are being shot from — these were things that id Software invented. On the other hand, from a story perspective, Doom was absolutely rubbish. You start in a room, no idea what’s going on and you are surrounded by demons. You have to read the manual and supporting media to get a grip on it all — something modern games would get heavily slated for doing. Yet the idea that plot was optional caught on and the same flaw was replicated in other games of the era, such as Quake and (to a lesser extent) Duke Nukem 3D. There were years and years where the lessons of early story-driven games were forgotten and all anyone really cared about was having as many sprites or polygons as possible."
