Conner in his starting outfit looks like Alexander basically, especially the version seen in KQ5! ...or Graham without a hat. Same kinda "rustic knight/squire/ranger" outfit Graham wears in the series just in a different color. Actually apparently early on they had toyed with the idea of Alexander being the hero in the game. Coincidently both Alex and Connor say similar epitaphs such as Zounds! All three share the same blackish hair and hair style. Alex and Connor look like they could be separated at birth.
Sorry Lambonius I don't think Sierra ever got real specific on the demographics for most of their games. Roberta did bring up facts about the gender demographics for KQ4 long after the fact but that's more so she could describe the controversy surrounding that game. From that we also know here earliest games also was largely a male player base.
According to a survey of the player's genders made after the game's release; it was asked if they preferred to play a male or female characters. It was found out that by in large male player base didn't care if they played a male or female character, as long as the game was good, and it fit and felt good to them. The female audience on the other hand, preferred by in large, to play a female character. They didn't really like playing male characters.
They might have said that KQ7 was more popular with women and children as well, but I'm not sure at the moment (I'd need to go look back over my notes). I know at least her target audience was intended to include young children that Disney animated movies often targeted.
Interesting note KQ8's target audience was teens to adults as far as age demographics. We also know it apparently outsold KQ7 (a game which probably outsold even KQ5 which was one of the series best sellers even outselling KQ6) but probably not Phantasmagoria at least in first year figures (which was Sierra's at the time of KQ8's release best-selling adventure game).
