2 things come to mind: a japanese comic called "one piece" had a character who used 3 swords at once by holding the third one in his mouth, and a character NAMED "Minmax" in this online comic: [link] (warning: very violent)
jeeze... I had to deal with someone like that... thought he was badass... I challenged him at one point though.... had a Bastard Sword I did, took his head CLEAN off his shoulders..... Don't care how heavy his armor was, Id' spoken, and he didn't ahve spikes covering that key spot on the armor lol....
*Played a thief with a retractable bastard sword... thing only weighed 1/2 of what the blades normally do, but i wasn't alloed to use certain skills while wielding it... hard to sneak around with a 22-handed metal weapon in my hand... also took 3 rounds to put it away, even if it only took 1/4th a round to draw it lol*
With "studying", I meant "scrutinizing"; analyzing every little stat bonus, every flaw and nook and cranny, trying to find loopholes, in order to make your character virtualy unbeatable. In other words, abusing the system. Also, the case with memorizing monster stats (because, you know, knowing how much HP a monsters got and what it's weaknesses are, even if your character has never seen that monster before, is totally good roleplaying).
Okay, now I get the scrutinizing part, but I have to disagree with the memorizing monster stats bit. If a player wants to abuse the system, then the GM can just change the rules/add own content as a countermeasure. If nothing else, that would be a great way to generate some real-life conflict (and drama is always worthwhile).
Hmm... I feel that my argument is flawed. Bah, nevermind, it's just a silly opinion anyway.
I find it funny that you mention the whole "wielding more weapons than you have hands" thing, because I did that once: I can't remember what all skills and traits I took, but the DM was EXTREMELY lenient in what we could do, so it was just a romping of doing whatever we thought was funnest, so i decided to build a Ranger pretty much like the ranger (or was he an archer?) from 8-Bit Theater, dual-classed ranger/ranger, took the Tri-shot skill TWICE (which meant SIX arrows at once, if i had enough) since having Ranger/Ranger let me, took Dual-Wield TWICE (Four bows), and I had maxed out my character's Dexterity, so I could actually manage it, I had some equipment that had made every one of my shots hit the target unless I rolled a 1 (we were playing critical failure 1 house rules), and we had come across a bottomless-arrow quiver, so being the Ranger, I got it. needless to say, being able to shoot 24 perfectly-aimed arrows at once was amazing for killing both mobs of weak creatures AND large powerful single creatures. among other insanely overpowered characters in our group was: a Warrior who had armor that let him resist 99% or physical and projectile damage, as well as complete immunity to poison and disease, and a shield that added that last 1% resistance to physical and projectile damage, plus full immunity to magic attacks and curses; a Druid who could change from one animal shape to another, and the animals' fur/feathers/hide/skin/whatever was made out of an enchanted indestructible liquid metal alloy; a Cleric who had divine protection from all kinds of protection and could call forth fiery death from his father (some hyper-powerful demon that was borderline-ruler-of-hell power); and a Bard whose dulcet melodies could soothe even the wildest of beasts (even the one time where we fought a horde of DEAF dragons, but apparently the resonance frequency of their scales gave them a vibrating massage that relaxed them (he rolled a critical-success 20), and they let us fly them to the Big Bad's lair AND helped us clear out everything) with a HARMONICA and once convinced a horde of moon-worshiping cannibal cultists to let us pass because we were envoys of the moon goddess sent to make peace with SUN-worshiping cultists, as evidenced by the silver tassels on his cap (again, another critical-success 20). It was the easiest campaign we'd ever played, but I'll be damned if it wasn't the funnest.
