For gameplay: Remble's finished A Creek without a Paddle and the sadly abandoned The Setting Sun.
...
For humour: Le Ran's For a Few ReincAARnations More.
Oh yes, these two are superb!
Not to say that others weren't superb, too, but these ones I will remember until I get old
I'd also like to mention General_BT's CK AAR Rome AARisen - a Byzantine AAR which is currently at, oh, 282 or so pages, and an absolute masterpiece of story telling.
