You made some great points in my opinion, but yet each one (Video game and woman) all have their pros and cons, just like I'm sure (Video game and male) has it's pros in cons in a woman's opinion.
1) They have an on/off switch ... Well, that can be said about us as males as well.
2) They don't complain when you play with them all day ... I love a lot of touchiness in a relationship but damnit not all dayyyy and I'm sure a woman is the same way, the video game might feel that way also but it can't talk, it just causes systems to overheat and you need a new one after a while, and that may be your sign.
3) They don't complain with you don't play with them at all ... I'm sure if you was to play with a woman ALL day for seven days and the next day she doesn't complain that you are not playing with her, I bet not, jeez you just played with your non stop for a week, I would need a break myself as a man and be like get off me woman lol
4) About setting their difficulty level ... I have nothing lol
5) They don't get jealous with you buy/play another "video game" ... Well the way you just put that is more like this ... You saying you want a woman/gf/fiance/wife that does not get jealous when you "buy/play" with another woman ... Well first off, playing with another woman while in a relationship is cheating and if you can't be true to the one you with, you don't need to be dating. And also, if you are "buying" another woman, you are doing it wrong my brother.
6) They don't follow you around after playing with them ... I would say this goes for young girls, girls that might have been a virgin before you met 'em and now they get clingy ... Same goes for guys, I have seen women, "put it on" some men and then the guy acts like a dog in heat.
All in all, video games are great - I do put some time away in the day to play my Black Ops, but at the end of the day my friend, I'm still looking for that woman that can be there for me, cuddle with at night time, make breakfast for in the morning, have great talks and laughs and just have that unbelievable connection.
Now if you are sleeping and cuddling with you video games, talking to it and making it breakfast, you might want to get the brain examined. =)
