I'm around 100 hours only in game. I'm beginning act 3, doing unending season. I'm 75% complete on dawnguard, and still have to explore the hearfire houses after this. I've done maybe half the side quest and ton of radiants.

Will dragon born be too immense for me, is it worth the money or the add-on in the game ? I'm thinking of going back for another 100 hours at least.

I don't think our advice will help you much as we know what's inside and you don't.

According to me, yes, Dragonborn is worth buying and playing. If you are short of money, Steam will probably have interesting sales for Christmas.

Of course its worth it. Best of the 3 DLC's IMO.

If you're on Xbox, they currently have a Thanksgiving Sale where its 50% off.

If you like Dwemer ruins as much as I do Sir, Dragonborn delivers.

If you like evolutionary 'stumps' pranging your crown jewels whilst mashed on 'dizzy drink', Dragonborn delivers.

If you like Dunmer banging on with faux cockney accents like blinking dike-Van-flipping-Dyke, Dragonborn delivers.

If you like...

(ding-dong)

Oh, wait I just need to get the door..

I think it's a tad overpriced at 20 dollars. 15 seems about right to me.

It is worth the money and it has a lot of content. It is more of an old school expansion pack.

Likely you can get a deal on the DLC in the next month or so due to the holidays.
