Well I'm currently running a female assassin rouge that's more into women but tends to be a snit. I think I'm going to hit for Isabella again.
I also am running my first guy rouge whoes kind of snitty but more compassionate. I did start a male mage who was really mean, grouchy and sarcastic but I scrapped him. I might restart him again in time.
Basicly It was like this for my guys:
Female casual but then mean rouge Kattie Hawke: Merril romanced, had a fling with Isabella, had no rivals, killed Anders, had no DLC. sided with Templars, killed Bethany mage ("YOU'RE NOT MY SISTER!" Damn how harsh can I get! lol) and donned anti mage after death of mother. Was my first playthrough so I wasn't expecting much. However I wasn't expecting to end the game acting so mean. lol.
Female mixed warrior Callica Hawke: Romanced Isabella, had a fling with Merril, spared Anders (character believes in repenting), no DLC, sided with mages since my background history for the character is she's a mage soldier herself, spared Bethany mage, fought and Killed Fenris (my character was so pro mage so she always disagreed with everything he said). Wasn't to bad of a playthrough.
Female anti mage mage (Oh the irony) Naturma Dite: Romanced Fenris, sided with Templars, Carver grey warden, Killed Anders, I didn't use sebastion that much but did his DLC stuff for achievements, had a fling with Isabella and Merril too as well as made regular prosthouse visits (my gal da ****). I wanted to keep with the character theme since she's based on a character I made for a story.
Templar then pro mage warrior of justice Vullia Hawke: Romanced Anders (Only to kill him at the end. It was so shakespear and emotional. It was awsome), Had no rivalries other than Fenris did temp side with Merdith but then he sided me afterward which I thought was cool since my friendship was near full with him, did it with Severan without anyone involved, Bethany became a grey warden (took the could care less approach even thought I was concerned for her), I was macking on Sebastion but didn't wind up with him after the death of Anders. :-C. Probably honestly was one of my best playthroughs for story reasons.
mage then pro templar kind of snooty, curious, and kind of evil Karakosh Hawke: Romanced Merril, had a rivalry with Aveline (even though I was macking on her and she kissed my Hawke, was semi hitting on Sebastion, had a fling with Isabella, killed Anders, Bethany became a grey warden (was yelling at Anders to help her but then was glad she was ok). Was an ok playthorugh. The only thing I kind of found interesting was I had Feyrinal become an abonimation to see what would happen. It seemed like it did nothing though.
