I like Roleplays in the sense of a roleplay that has structure and story behind it.
Such things as Family Rp's, which are near-identical versions of each other, and consist of people simply pretending to be a child or adult, or taking it one step far and pretending to have love, just aren't my cup of tea.
I like a slight bit of sophistication with my imagination and games of fantasy.
But, I also quite like TDM's, if the sides are fair and I'm not lagging to hell, which I unfortunately often have occur.
And them, a good old themed build is nice too.
And other than that, I just enjoy spending some time on my server with some friends.
