That said, if a given set of mechanics are forcing me to dream up more narrative and-or more detail than I or my group really want, I'm going to end up either ditching those mechanics or bailing on the narrative details.
Sounds perfectly reasonable. FYI... the level of narrative gloss applied to power use varies quite a bit in my group; it all depends on people's mood and energy level. Sometimes we just use straight power names and numbers, other times we dress the raw mechanics up with a good bit of fiction.
Even when we're tired we usually manage
something to tie the mechanics to the game's fiction, even if it's little more than a character's catch-phrase, like when our Communist Avenger --who's Avenger powers are powered by something called "Dialectical Materialism"-- declares an opponent "an enemy of the people".
But, if you see "opportunity" in 4E, then that says to me that you were just missing out in whatever game you are comparing it to.
Missing out in what way?
So if you were not doing this in 3E, you ARE now in 4E.
Oh no, we did the same thing in our 3e campaign; attached our own fiction to the official game mechanics. All the time. In great, heaping bushels. Of fiction. The only difference was in our 3e campaign we were usually replacing the fiction which was already attached to the mechanics, whereas in 4e we were usually
attaching fiction to mechanics which didn't have any, or at least enough.
In both games we made a lot of our
shi stuff up (and ran with it). In neither game was this seen as burdensome.
A good game of 3E is much better than a good game of 4E.
For you, sure. For us, I'd say it's a wash. The truth is our 3e and 4e games are very similar; the focus is on bold, outlandish, and more-or-less morally indefensible characters exploring and working their will on detailed fantasy worlds which sit right on the (disputed) border between homage and parody (and satire and surrealism).
Likewise, if you play 4e like 3e, you probably aren't getting the best of what 4e has to offer.
Like I said to BryonD, my group is playing 4e a lot like the way we played 3e... could you go into a bit more detail? (did I just RC to
expound on something??!!??)
