This thread is super old but I'm so in love with Dragon Age honestly. And ignore my post for spoilers from DAO, that game's old but I guess some people may not appreciate it.
I just finished a Mage playthrough of all of the games and DLC's. Elven Mage Warden named Aoife, Mage hawke, and Dalish Mage Inquisitor.
With my Mage warden (the first Mage I actually finished as), I played as an Arcane Warrior/Spirit Healer/Battlemage spec and totally annihilated everything. I had a party with Shale, Zevran, and switched the other spot with Morrigan and Wynne. That was also the first time I managed to play through the whole game on nightmare. I made some pretty questionable decisions I'd never made before on that playthrough, like sparing Loghain. And I actually ended up being friends with Loghain (I even got the friendship dialogue with him), whereas Alistair had about -10 influence by the time that play tough was done. I used the feasts at gifts to raise his approval to get his quest and harden him, then used feast day pranks to get it back where it was before and let him hate my guts. Then I got to Awakening and became best buddies with Nathaniel Howe and Anders. Anders' approval even glitched and at +100, it showed Love instead of Friendly lol. I spared the Architect and burned Amaranthine to the ground and then lived happily ever after with Zevran.
Then I got to DA2, and that was pretty decent. Very short, but decent. My Hawke was a Force Mage/Spirit Healer named Brennan and my main party was Varric, Anders, and Fenris. Aveline bugged me. I just left Fenris home on all the Mage quests and still got his friendship to +100. Carver became a Warden, Anders was spared, and I sided with the mages. Sebastian hated me and decided to retake Starkhaven, I could never get Avelinems approval up or down enough because one minute she would approve, another she'd disapprove. Oh well. Hawke and Anders ran off like Bonny and Clyde and their pet Justice.
My Dalish inquisitor, Sulahnera, hated the chantry, was best friends with Solas, literally got Vivienne's hate dialogue the second time I went to Skyhold, made some pretty pragmatic decisions that I won't say in fear of spoiling the entire game. I romanced Cullen on that playthrough, because Solas makes me angry for reasons and I wanted to see what his dialogue would be with a female Mage warden import.
I literally finished all of those playthroughs in 2 weeks. Now I'm doing a City Elf female named Maeve that hates humans, is best friends with Morrigan, Sten, and Shale, and is romancing Zevran. Pretty chaotic neutral, makes choices out of necessity without really caring what happens. I actually killed Isolde. Had no regrets for slaughtering everyone in the Arl of Denerim's estate and absolutely hates humans. Alistair and Wynne absolutely hate her guts so far.
I've had tons of wardens though, I just really like seeing the different endings. Sparing Loghain actually made me really, really like the guy, especially after reading the books. *spoiler* and that made the Into the Abyss decision so much harder.
Among the 500 wardens I've had, the other ones that stick out are my Dalish Warden named Dahrana, who romanced Alistair (yuck) and kept him as a Warden and made Anora rule alone. That was pretty fun, but I really don't like Alistair that much so it was kind of cringey to romance him.
Then there was my Aeducan, Firah, who hated Trian and hated Harrowmont and hated Dwarven politics. That was really fun in the Orzammar chapter. Otherwise, pretty lawful neutral sword and shield type character.
