"storyline-driven game without a proper storyline"
Sorry but I won't get into a debate on differences of opinion over something this trivial. Argueing opinion for trivial things is like trying bang ones head into a railroad spike over and over again. You aren't going to convince me to agree with you, and I am not going to try to convince you to change your opinions. I may not think MOE has the best story of the series, but what there was I still enjoyed. If you didn't like the story fine.
Unfortunately we never got the entire story as it was originally intended, but only hints at what it could have been, as practically everything that would have made it more like a traditional adventure game story was either never completed or cut thanks to Dynamix screwing up the game's engine, forcing Sierra to finish the engine themselves. Because of that they didn't have time to finish most portions of the game and were forced to release the story butchered, due to a strict deadline for the release date made by company that owned Sierra at the time.
Maybe things would have been different if Ken Williams hadn't sold Sierra out. But its too late to worry about that, and the change seemed to have affected most of the sierra adventure games at the time. Several games from classic sierra adventure game series were cancelled, and those that were released were not as good compared to previous games in the series. There was something really wrong when Sierra started making more clones of other companies games, instead having original ideas...
