Hi,
well...I found a dragon but he is not attacking me. Should I kill him?
They are supposed to be our allied right? I just killed those who attacked me. maybe there are good and bad dragons? I don′t know, this game is huge.

wah??? you killed two dragons? you monster!

dragons are your friends in this game, you should be riding them, not killing them

I tried attacking such dragons, seems you can't even touch him.
And just for record, they are ignoring you. They are still bad guys who want to burn every town and village to crisp.

i learned if a dragon doesnt agro u, your not in his agro zone. u must be moving to a certain spot before they agro u, this spot is pretty big but isnt always easy to find since dragons fly over such a long distance.
i tested this out btw. at first i thought some dragons are part of the scenery and are ment not to be attacked but thats not true. if you dont move in their agro zone within specific time they just leave again. but if u do catch his attention by moving to the right place they change to agressive.

Bring a dog, it'll make the dragons drop. It's a glitch. But yeah, all dragons are EVIL. They look awesome, but they have to die.

Not all dragons are evil. Barbaric pigs. Just like the Blades.

It seems their are bugged out enemies in this game then. I ran into a giant today that didn't attack me at all, There was no talk option either. I didn't want to try and attack it due to the starfish flying bug but I don't think he would have hit me back or even been hit by me for that matter.

wrong thread? btw, only camp giants attack u. not travelers

How did you come up with this being in the wrong thread? It perfectly matches the problem the original poster is experiencing with this dragon.

ok,dragons good only if they don′t want to eat me.
I do kill giants and mamuts though

That's not a bug. Giants are not very aggressive, they usually don't attack unless they think it's a threat to them or to their mammoths. If you get too close, they'll usually try to intimidate you first.

This one was walking with one of those farmer's marked cows and he didn't threaten me in any way. He paid no attention to me at all.

The **** is a mamut?

I think the OP means Mammoth

XD!!!
mamut = mammoth in spanish...

Ehr.. You know wha to bet "Dragonborn" means? If you already saw two dragons in the game it should be clear to you by know..
