Well u guys know. These 4 guys have their abilitys.For those who played Dragon age knows that the grey warden killed tons of things in lass than a year and save the world from the "blight" from a "demon dragon god" with thousands of creppy monsters at his back.Also he garthered an army,something that dovakhiin didn't done.But could he with his insane abilitys defeat the Dragonborn that posses the Thu'um power,and in that case would FUS'ROH'DAH' him the first sight.
Now the Archdemon and alduin,well alduin is a god that breath,fire and ressurect dragons(so he would ressurect high dragons to help him?) ,is immortal and calls fireballs from the sky.As the archdemon,he is immortal fire darkness breath have thousands of minions and if he not dies in the hands of the wardens he ressurects in other bodys.
I want to know who is the most badass medieval characters from those two games.

The grey warden is just a regular folk that drank darkspwn blood but he doesn't have any special power, except for sensing darkspawns and killing Archdemons. I'll pick the dragonborn here because the thu'um is awesome.

As for the big lizards I must say I had a tougher time killing the Archdemon than I had killing Alduin. So I'll go with the former.

actually i am pritty sure if the thane of all the jarls in skyrim wanted to gather an army plenty of people could be ammassed.

Still on the comparison subject:

DA:O had a better story, lots of choices that actually made a difference at the end. But there was no open world and the fact that you were forced to fast travel kinda broke the immersion. It felt more like an epic movie then a real RPG. Not that it was bad, it was just different from TES.

On the other hand Skyrim is a better RPG because you have the freedom to go and do whatever you want from the get go. It feels like a virtual world where you can immerse yourself for hours just doing silly stuff like catching butterflies if you feel like it.

Worry less about the outcome of hypothetical fantasy battles and more about your grammar.
