Time for some controversy!
Here is a short list of games which I have played that were sold as the greatest thing, like, EVER and which not only failed to ascend the Ziggurat of Excellence, but just barely managed to reach the top of the Staircase of Mundane and Pedestrian.
4. Oblivion
For a long time I thought the problem with Oblivion was that it was just unfinished, and that if they had bothered to kill the bugs and make the graphics engine work as advertised the game would have been great. Looking back, I see that the game was broken at a more fundamental level. It’s just that the bugs and graphical problems masked the deep, underlying design flaws.
Auto-leveling loot and monsters neutered the level-building aspects of the game. The voice acting (instead of text-based interactions) limited the depth of dialog, and made sure you heard the same handful of voices no matter were you went or who you spoke to. The main plot was so bland someone actually introduced a mod to get rid of it. The one strong point of the game - a huge, sprawling sandbox world - was glossed over by letting the player teleport around the map via the auto-travel.
Bugs aside, this game was not awful, but it also wasn’t the ground-breaking Game of the Year everyone made it out to be. If it hadn’t been a descendant of the beloved Morrowwind and a benefactor of a good bit of hype, I think it would have gotten the treatment it deserved: A nice effort that failed to meet the standards set by earlier titles.
