4) Improved Graphics
The pink pinches of pigmentation lying on the horizon in the Fallout 4 trailer seem to suggest that we may be in for a slightly less sickly-colored setting than with previous installments, and whilst the teaser seemed to indicate that the graphics weren’t quite flawless, it’d be great to have an improvement on the glitches of New Vegas. Ghosting your way through solid rock and becoming trapped in the wasteland whilst the rest of the game obliviously raged on without you was never a fun experience, but one can only hope that these kinds of glitches have been wiped out for the next entry.
Another nice addition in terms of graphics might also be the inclusion of some complex weather conditions that force the player to scramble for shelter. The sprinkle of nuclear ash or lash of acid rain could really inject some panic and excitement into otherwise ordinary gameplay moments, serving to help players out in certain situations and severely endanger them on other occasions.
