I don't care about gaining levels/getting good equipment i play on easy and have some mods that gave me some cool equipment. I'm just curious if they effect the story at all as i'm looking to play this game 6-7 times for different wardens all in preperation for DA:Inquistor and want to know if i can skip the majoirty of side quests.
Then you are like me. I never bother with them. In fact, they feel like they detract from the story and the character I am running. Some if you want to be a bad guy could do that like I think the Crows but I've never done them. I got roped into some and hated having them clog up my journal. After the first and second playthough I quickly learned to avoid certain people and conversations. They have pretty much no impact and really if you are doing a play where you really have your character running against time to stop the blight, doing them is out of character. They really don't matter - sides quests that is. I've played at least 6 or 7 characters already.... maybe 6 I think, and only in the first did I really bother. Now I have a store mod that looks like flemeth's hut where I stock up on massive amounts of things (because I use the toolset to mod what I can carry so I don't have to keep stopping and can bring it with me into awakening) and it's all free. That might be the best mod ever. And I find it so much easier to just immerse myself in my character who is trying to stop the blight that way. I even roleplay the store mod as a supplier for the Wardens that nobody knows about. Has everything we need and plenty of it. Comes from a long line of Grey Wardens but was no warrior himself so decided this was the next best thing he could do. Wardens funded him well....
So in short, I have no done a single side quest barring maybe saving valenna in the castle in many games. When Perth asks me to get the blessing for the troop I say okay, then end the conversation then restart it and say I'm ready. No running all the way down the hill to get medals that don't change anything. I might give the corpse gills I collect to the chantry though because who wants to carry them around. I might kill the bandits running around the edge of lothering for fun if I feel like it but I don't go back to get paid because I've got money.
Roleplaying, the best of it comes from choices you make on big stuff. In a game like skyrim you could join different factions and follow their questlines and that would truly add to the role playing, but not really here as far as I can tell and not to the overall story at all. So if you want to blow them off, then go right ahead. None of my games have ever suffered and nothing really carries over into future games, not even the major decisions as far as I could tell beyond if I made alistair king and what the boon was and that was a mention at best.
