As most of you can tell the wasteland is a little geographically small. But packed to the brimm with shtuff to do. I think this is going to be a DLC heavy game just like 3. but better.

Necessary thread is necessary.
Yeah but I wonder how they will use the DLC's.
Will we get PL kind of DLC's with open areas.
Will we get dungeon crawlers like O:A or MZ.
Will we get expansion upon the main game area like BS.
Will the DLC's open up the main map more?

Only time will tell.
But I'd prefer PL kind of DLC's with open areas.

That will probably depend on the number of sales. Hopefully the game will do well despite the technical issues.

We went through the same the with 3. Give it sometime patches are already out. Play on pc and you wont have any (many) problems.
