I play on Easy because I'm a wimp.
Cimora Cousland v1:
- Missed origin sex, Chasind trail, Shale, Soldier's Peak, Leliana's and Sten's personal quests, various side quests...hence my intent to replay this character.
- Saved Redcliffe Village and got Lloyd killed in the process, sacrificed Isolde, encouraged Teagan and Eamon to let Jowan live.
- Helped the mages, let that one blood mage go, and killed the desire demon with the bewitched templar.
- Got Zathrian to end the werewolf curse, brought Cammen and Gheyna together.
- Sided with Caridin and put Harrowmont on Orzammar's throne.
- Killed the Tevinter slavers in the Denerim alienage.
- Lied to Morrigan about killing Flemeth.
- Did not harden Alistair.
- Won Zevran's loyalty.
- Romanced Alistair and ended up becoming his queen.
- When jailbreaking Anora, surrendered to Cauthrien and then escaped Fort Drakon without outside help (posing as newly recruited guards and leaving "on patrol"). Later conviced Cauthrien to let them into the Landsmeet peacefully.
- Cimora dueled Loghain herself and then let Alistair finish him off.
- Anora is rotting in a tower. Told her she'd have her support in the Landsmeet and, obviously, didn't mean a word of that.
- Did Morrigan's ritual.
- Stayed in Denerim after the epilogue, asking only to continue serving the crown, while Sten returned home, Leliana went after the Urn of Sacred Ashes (and failed because the local dragon wasn't slain), Oghren stuck around, Wynne became an advisor to the court, and I'm not sure what happened to Zevran.
Ganin Tabris:
- Slaughtered pretty much everyone in the estate during the origin story, including the Arl's son and his cohorts. Took full responsibility for the incident in attempt to shield Soris.
- Saved Redcliffe Village but failed to kill off Lloyd and instead gave Bella money to leave and find a better life for herself. Went to the Circle for help against Connor's demon. Rescued the mages, let that one blood mage go, let the desire demon and the bewitched templar go, and upon returning to Redcliffe he had Wynne go into the Fade. Didn't care what happened to Jowan.
- Got Zathrian to end the werewolf curse, brought Cammen and Gheyna together.
- Sided with Caridin and put Bhelen on Orzammar's throne.
- Killed the Tevinter slavers in the Denerim alienage.
- Having "romanced" Morrigan initially, Ganin killed Flemeth. There was no romance between them as far as Ganin was concerned, but eventually a good friendship developed, even after he left her for Zevran.
- Zevran + Ganin = Love
- Hardened Alistair, did not harden Leliana, retrieved Sten's sword, earned Shale's friendship.
- Fought Cauthrien when jailbreaking Anora and defeated all but her and one of her soldiers before succumbing and being thrown into Fort Drakon. Escaped by seducing a guard, snapping his neck and taking his uniform, and then stealing a password note.
- Had to kill Cauthrien before entering the Landsmeet.
- Told Anora she'd have his support in the Landsmeet but put Alistair forward instead. Ganin dueled Loghain and then let Alistair finish it.
- Agreed to Morrigan's ritual, bedding her himself rather than making Alistair do it.
- Returned to the Grey Wardens after the epilogue. Zevran accompanied him and helped to train new Wardens, though never becoming one himself. Ganin asked Alistair to elevate the elves and so Shianni became a bann. Shale went to the Tevinters to see about restoring her mortality and dwarven body, and Wynne accompanied her. Leliana's expedition to the Urn of Sacred Ashes succeeded. Sten returned home with his honour intact. I'm not sure what happened to Oghren.
I apologise for the long, boring post. xD
EDIT: Eek, it's even longer than it looked in the fast-reply box.
