With Fallout 4 you should expect an insanely deep level of character customisation options. Some players have accused Fallout 3 and New Vegas of being a bit light when it comes to this element of the game. Stating that they sometimes weren't RPG-ish enough. This will surely be remedied in part 4, with an increase in the number of attributes, skills and general customisation options available. It's doubtless that Pillars of Eternity and Tides Of Numenera will arrive with some complex, D&D style character customisation options, meaning the Fallout 4 developers will need to make this aspect of the game the best the series has seen. Expect to see a mixture of depth and accessibility: enough for RPG veterans, but not so much as to put off newbies to the genre.
