Maybe, I always interpreted the dunes change as a game design change rather then a lore change, but it's possible. Generations surprises me, because they've reworked a lot of old areas to account for the gameplay style, whether this also affect the lore or time of the areas I have no clue. Personally, I am not a big fan of adding random small ledges everywhere, but it's understandable the purpose they serve. The other thing that intruges me is the NPCs not aging/changing (visibly), they have often referenced older events from their respected areas, but maybe this world changes more rapidly then our own (which due to the nature of elder dragons is entirely possible) or aging is much slower. Before I get too side tracked with this, there is one thing I can with certainty, you definetly do not play as the same hunter/person in each game. Anyway just some food for thought...
