I play an extremely generous character. Why? Two reasons, mainly.
First, I like making other players happy, as my character likes making many other characters he knows happy. Or at the very least, healthy (because nothing keeps the doctor away better than a trusty blade at your side).
Second, he has way too much junk sitting around. I'm a packrat in real-life - I have a very difficult time getting rid of things into the void, especially middle-to-high-end items. Giving things away helps both clear out the junk I keep, and doesn't make me weep for throwing away (or close to it) something I spent four months, RL, saving up for. (That's one of the reasons I don't really mind item loss on quests - so long as there's a good RP reason. For that matter, there's not much I mind, with decent RP along with it...)
But, with the exception of low-end scrolls (fireball, darkness, etc.), there's almost nothing that is purely a gift. The only character Pyyran's really given -gifts- to is his beloved, and that's just (off-hand) a sword or two.
I've traded a crate of booze for a reinforced clothing (altered it to fit the other man!), scrolls for whatever jink there was to be had, gear for other assorted gear... Nothing's free. Not in life, not in the game.
But the initial post wasn't really about piecemeal deals. It was about wholesale "I have plenty of gear that you can use" sort of things. High-level characters often DO have full sets of gear for mid-level characters! It's really not hard to pick up all sorts of nifty junk; just need a good group and a bit of patience.
But... For each high-end craftable trinket that drops, that's another crafter who's worked for years - even RL! - to be able to make that sort of thing... Who now is out another of the few high-end customers there are.
Pyyran doesn't have a single emerald. Never has, except one that he inherited - along with the 100k worth of debt that went along with it. Best thing he has is probably the cobalt-reinforced clothing he's had since level 13... And he's been around for a long time, with plenty of high-level friends, IG and OOC.
Still. Let's think about that mithril fullplate you pulled off some dead orc. Can YOU make that metal into something suitable for your elven buddy Sidrak? (For FULLplate, it should actually take a full resmithing between two humans of dissimilar build. That point of max dex comes from the fact that it's a highly-articulated piece of equipment, very custom-tailored.)
