There are a lot of similar mechanics between the new fallout-4 and the previous fallout 3 and New Vegas games.
When the mechanics are the same between games:
Is it appropriate to tag newly asked fallout-4 questions with fallout 3 and fallout:nv? For example:How to hack terminals
Further, should we add the fallout-4 tags to questions that pre-dated the game? For example: How can I automate the hacking minigame?
