Pshh, Skyrim has been installed to the HDD since last year when I bought it
Hmm, tips for Fallout...there's thousands but the mains are are as follows:
Save often, like every 15-25 minutes. Vary your playstyle in order to make good progress for the 10k points of damage with each type of combat (melee, unarmed, explosive, energy weapons, standard weapons, etc.). Once you get the The Strip, make FOUR different saves because there's four different ending and replaying the game would be a pain. Use the Achievement Guide & Roadmap religiously as some achievements are confusing, as are the methods in reloading that one save to branch off and get all four endings.
In terms of DLC, do them in this order: Lonesome Road, Honest Hearts, Dead Money, Old World Blues.
I hope you have fun and if you have any question, lemme know, punk.
