Inquisition, while theres things a love about it, had a piss poor open world. It had all the cliche problems of open world games, vast stretches of nothingness dotted by boring fetch quests. There were fun and great quests in the game but they were space out too much. Inquisition would have been a much better game if it had dropped trying to be open world and just stick to DA: O model of having smaller areas you can explore, loaded with quests. It worked so well for DA: O and Mass Effect before they tried to be like Skyrim.
I'll wait to see how the game is once its released before deciding whether to buy it or not.
