Wow, I really like the idea of offering different items & food to different Divines! I may just have to steal that idea!
My paladin throws various items (books, gems, cheap items etc) into the altar, too. But she doesn't go as far as yours.
My paladin (Dyan phor-a-Cauz) will also spend ALL DAY or most of the day in a Chapel if it's Sundas and she happens to be in a town. I've noticed quite a lot of other NPCs will join her in Chapel, too, if it's Sundas. Nice touch. It's kinda like a Quaker meeting, though. Nobody really preaches anything. Everyone stands around or sits around mostly in silence. Main difference is: instead of bringing up inspirational thoughts (as Quakers do) the NPCs in Oblivion (if they speak at all) wind up saying all the usual random crap they always bring up.
Anyways...here's some more ideas...my paladin...
> wears the commoner clothes if she's not dressed for battle, not the stuff royalty and upperclass NPCs wear.
> Has a very low ego. She does good works for the Empire and for the NIne Divines...occasionally for another NPC (quest), but never for self-serving reasons.
> She "tithes" to church members, and gives a tip to stable-hands, poor members of society, etc. I do this by pushing the "Bribe" option, although I'm pretending it's not a bribe.
> She NEVER passes a beggar who's asked for "a coin" without giving. One excpetion is if the beggar happens to be a lizard-person or cat-person, then it's like "Come on...you can get out in the world and hunt" Human beggars in the game usually LOOK as though they're sick or ailing and in need of assistance...
> No murders.
> No assaults (not intentional, anyways).
> No stealing
> No bounty (obviously). Ever.
>she only keeps enough money on-hand to equip a basic amount of sustenance/weapon/armor upkeep. She's gonna be my first character who isn't in this for "the money" or the fame, basically.
> No displays of excess. She's going to buy the Waterfront shack and Bruma house (she's a Nord) but not fully decorate them. Again, to me it seems a paladin is not on an ego-trip. Not trying to show how great he or she is with this giant, expensive house.
>The one exception to the "no excess" rule is that Dyan does occasionally carry an enchanted or silver sword, or enchanted armor. She like heavy armor, too. But all of this is in support of the Empire & Nine DIvines.
> According to D&D rules, Paladins also can have limited magical powers, too. In Oblivion, this translates to: various Restoration spells, Convalecense (however you spell it), Detect Life, Turn Undead, Light, and possibly Sheild spells on occasion.
> She uses scrolls & potions to augment her sword skilz, occasionally, too, but mostly she's all about the Blade!
