Your first character with a Prestige Class

[Kae'Yoss]

That was my Bladesinger (also my first 3e Character, too). And the character was supposed to be a bladesinger from the beginning.

(edit)
Ah yes: It went really well.
He was supposed to be the party warrior, and was able to dish out a nice amount of damage despite the sub-optimal fighting style (longsword in one hand, nothing in the other). He got one level of wizard, 5 fighter, and then I filled up with bladesinger (with 4 levels of divine champion of Corellon to bridge the gap between PrC level 10 and epic levels). He didn't have the most HP in the party by a long shot (druid that started with 18 con was so far ahead...), but with his magic he could render himself a good way toward untouchable (real nice AC plus other effects - mirror image, that puny 2nd-level spell, saved my hide so many times it's not even funny).

He was also the paragon of everything elven and the concept of Chaotic Good (much to the chagrin of the CN megalomaniac wizard in the party), and defended the elven way against everything. He became (roughly in that order) most powerful bladesinger of faerûn, chosen of Corellon (though without any mechanical bonuses), and, at the end he ascended into the elven pantheon as demigod of bladesingers (though that was in the aftermath, I didn't get to run around as divine entity). Funny thing: in our current campaign, which plays a little after the first one (though without direct link between the characters or storylines), we have another bladesinger in the party, and he is a follower of my former character, and his master was the first pupil of my old character.

Wizard/Alienist. My elven wizard had a close-up and personal encounter with the Elder Elemental God (Greyhawk). Me and my DM agreed that it would be cool if he started getting alienist levels instead of normal wizard levels. So he was a reluctant alienist, rather than one who actively sought out terrible secrets. Instead, the secrets came to him (via hideous dreams).

As a DM, I love PrCs. My bad guys have loads of 'em. I write new ones, too.

As a player, apparently not so much. I've run a Ranger/Rogue, two Druids, and a Cleric -- no PrCs at all. Hmm.

[shilsen]

My ranger/rogue/deepwood sniper. Most enjoyable PC I've ever played, not because of the PrC, but because it was the only PC whose character I based purely on myself.

 

[Lord Morte]

My first was Sir Tearlach, a Paladin of Pelor/Knight of the Old Kingdom, who tragically went insane after the party decide banishing all gods was a good idea.

He was fun, though. The archetypical big, dumb knight who on one memourable occasion rampaged through a pair of mind flayers with a lance.

 

[Jdvn1]

Tribal Protector. The extra attack, along with the TWF feats made for a really cool combination.

 

[CronoDekar]

I've never used a prestige class as a player, actually. It's not that I don't like them -- I love them, in fact -- it's just that either 1) I couldn't find one that both fit the character concept and provided me what I wanted out of the class, or 2) they just never got to a high enough level to attain the prestige class. My first character (a sorcerer) was going to take Divine Oracle, but that camp ended the level before he would've taken the level, and it happened again with a Cleric/Fighter going Auspician.

As a DM, I've used several, though usually the characters with them didn't see much action. The first one I probably used in battle was probably a Divine Agent, though she only had a couple of levels.

 

[Darth K'Trava]

A cleric I had who went for Divine Champion because she'd had aspirations of paladinhood but didn't want to go by all the "rules" paladins do. Not to mention that it would've been an alignment shift from NG to LG to do so.

 

[Remathilis]

I had a cleric grab the original radiant servant of pelor...

Broken then, broken now. I loved it.

 

[TheBadElf]

Heh...that would be my created-as-an-epic-character gnome Druid / Shifter. He was fun; I pulled off some wonderful stunts with him. My group still shudders at the memory of the "turn into a really huge Bone Ooze while in the middle of a formation of elite hobgoblins" attack. RIP Tobbin Greencap, lost in mortal combat with an Infernal. Darn at-will Blasphemy...
