he he, there are some nice ideas.
Serously I would got for some dating events and more after marrage events which are exclusive to the girl you marry (I think that HM 64 had this, if it did, why did they take them out)
Anyway here is my version of the dream event which I heard about:
Farmer walks onto beach
Farmer:
Rick: So you finally figured that it was me who did it
Farmer gets sickle out
Rick: Don't bother, I can kill you in one attack
Farmer:
Rick: BOW DOWN TO THE MIGHTY CHICKEN
Rick gets a chicken from no where and throws it on the ground
Farmer
Chicken: chock a doodle do
Then swarms of chickens come out of nowhere and attack the famer
Farmer:
The farmer slices some of them but gets overwhelmed at the end
Rick: (while farmer is getting mauled by chickens): All your base are belong to us.
So how is that, I don't think Karen is evil enough. (That was one of my attempts to be funny, which I don't think are very good)
One event that should happen is that if you get all the girls/boys up to red hearts they should then realise that you have been hitting on all of them. There are two possible outcomes that I see.
X rated version: They all relise that they all love you and all of them decide to marry you (think of what the wedding would be like). Congratulations you have just commited polygamy.
Normal version: All the girls/guys decide to beat you up. Then all the rival guys/girls gather around you and go "Ha ha!" Then the game over screen appears.
That what I think.
