I personally liked Rance because of his antics.
I wouldn't be loving the series as it is if Rance wasn't who he is.
Personally, the rape and random killing serves as entertainment in the game, though as the other guys up there, I wouldn't want anyone in reality to experience what the different characters in the Ranceverse go through.
After going through all that, Rance is just a person too. I like how his character develops. Well, at least I see a development. But anyway, the lore is awesome.
I know that rape and murder are not acceptable. Yes, they aren't acceptable in our society. But let's be nice at least.
If you don't like the game, then leave it be. There's no need to drag others down into your disapproval of it. It's just a game.
But I am okay with people hating on it. Just don't hate on the people who play the game too. <3
