Enchantermon: I was referring to the XP compatibility sliders. At least, I *think* they're available in XP; they might actually have been phased out by that point.
If I remember correctly, you have to go to the desktop, right click anywhere, select properties, go to the Display tab, then click "Advanced". There should be a series of tabs on the window that then opens. In one of them is a slider that will allow you to alter graphical settings. Ideally you shouldn't pull it more than two or three slots to the left, because that would disable DirectX and make the game unplayable. But I found playing with them useful when I was getting old games working. It was essentially the older version of Windows' compatibility modes.
I agree that 7 isn't the best in the series. I don't mind the Edgar retcon - I mean, the games consistently retconned throughout, such that Manannan had no brother before 5 and Cassima was just a kidnapped princess between 5 and 6. But the whole thing felt very cartoony. I'm also not sure how I feel about bringing in the Fates and the Dream world: they're such important things, which underlie all of human experience, and they were really just sort of brushed over in the final chapters. I also found Rosella kind of annoying. And Falderal drove me crazy.
Having said that, it still feels like more of a KQ game than MoE. It's still an adventure game, and it still features members of the royal family. That's not to say that I prefer it to MoE *as a game* - like I said, I think MoE has a lot going for it - but I do at least think KQ7 was a reasonable (if not brilliant) addition to the series. MoE just didn't really belong in the KQ series at all.
