I loved my snarky ginger-haired 'take nothing seriously' Kit Hawke. It took approximately 10 playthroughs to find my 'canon' but she's it. I still had other favorites though. My first, unspoiled playthrough had 'forever alone' Isabeau Hawke--in which I lost half my crew and ended up having Nathaniel and Zevran fighting Meredith at the end with me. The first time I rivalmanced Fenris was on my pacifistic diplomatic mage, Lily Hawke. The first time I fully rivaled Anders (and gained new appreciation for his poignant--and doomed--struggle to maintain his humanity) was on my aggressive mage, William Hawke.
I enjoyed all three games on their own merits, and found each game offered new opportunities to explore aspects of the writing.
However, once I installed Inquisition, I haven't been back to either two of the earlier games. Mostly because I have limited room on my PC and they were too large to keep on my hard drive. I'd go back to DA2, though not Origins, mostly because I hate the warden's silent mannikin stare and mute responses.
