Okay, forget anchors, obviously everyone else loves them. So going on to other arguments, now with examples.
Let's look at Ramza from FFT for a second.
Ramza Beoulve
Squire ("Uber-Squire")
Brave 70, Faith 70
HP 164 (394) [280] {284} <334>
MP 69 {106}
PA 9 [13] <11>
MA 9 (11) [11] {15} <11>
Sp 9 {10} <11>
PhysEvade 40 {10}
MagEvade 15 {50}
Can equip Swords, Knight Swords, Daggers, Flails, Shields, Hats, Helmets, Clothes, Heavy Armours, and Robes (o_O)
Rune Blade
Crystal Shield {Aegis Shield}
Crystal Helmet [Twist Headband] {Flash Hat} <Thief Hat>
Crystal Mail [Power Sleeve] {Wizard Robe} <Power Sleeve>
Battle Boots (+1 Move -_-)
Physical Attack: 126 [182] <154> damage.
GUTS:
* Ultima (10 MP): 106 {144} magic damage. (Ignore Reflect/Evade)
* Dash: 9 to 36 [13 to 52] <11 to 44> random damage. (Ignore Evade)
* Scream: +10 Brave (worthless), +1 PA, +1 MA, +1 Speed for rest of battle. Stackable. Self only.
* Heal: Remove Blind, Silence, and Poison.
* Wish: Ally only. Ramza loses 20% of his Max HP in HPs and gives double that number to an ally.
Special notes: Scream adds exactly 14 extra damage per physical attack, and 9-10 extra damage per Ultima, per use of Scream.
This is pretty good as a quick reference. It quickly lists his optimal setup if he needs raw durability, physical damage, or magical damage and denotes them in a way that's understandable if you look at it for a minute.
But, supposing you don't know FFT like the back of your hand, you might not know how potent that equip list is. Fortunately, you can scroll up a bit and see a nice list. This is fine, saves space and clutter by not having every single equip option by every single character.
On the whole, it works fine... if you're familiar with stat topic conventions and the game in question.
Now, suppose you gave Ramza his own page. Rather than this condenced version you'd have in the main topic, you could give a few sample setups, noting when he might need each of them, list all his alternate equipment right there with him, so say an RPGmon ref can just go to one page and quickly know what options to account for, and possibly even explicitly note what all statuses and elements he can resist and to what degree, or even what doing that costs him. Hell, you could put biographical data and the like on there too.
Or for a completely different example, Fire Emblem. You have the PCs in a big stat chart with averages listed at the bottom, then lists of weapons elsewhere in the topic. Again, good for saving space and functional if you know how FE works, but it amounts to tossing your reader pieces of a puzzle and making them assemble it to get a complete picture of the character (plus the charts are so big they don't fit on a screen. Whee scroll). It gets the job done, but we can do better now that we're devoting an entire wiki to it, not just forum threads.
Nevermind that, and I honestly thought this would have been obvious, doing it this way gives you something to link to the character from the arena (or at least their record).
