I just remembered a couple of examples from games I played at GenCon this year. (I can still say "This year" for another 13-and-a-bit hours!)
In barsoomcore's DPNI game, I was playing a ninja... my attack and damage bonuses were significantly better with my sword than empty-handed, but I didn't draw the sword until the last round of the last combat of the adventure, when we were fighting the Slave Queen herself. None of the opponents until that point were worthy of the blade, y'see. So I punched, I kicked, I tripped, I grappled, but I didn't cut until the BBEG showed up
In Alenda's Halfling Musketeers game, I was given a pregen swashbuckling halfling, and it said in his description that he fought with sword and dagger. "Question," I said. "It says sword and dagger, but there are no two-weapon fighting feats on here... is that right?" "Oh," I was told, "the dagger in the description is really just flavour. You don't have to stick to that." "Ha!" I ha'd. "TWF feats are for wimps!" And I spent the adventure taking a -4/-8 penalty to my two-weapon attack rolls, and nobody could have buckled more swashily!
