Video game to RPG tropes are most relevant in both series. Both franchises embody a wishful fulfillment of enlightening the audience with monstrous attacks on the heroines, within SAO, for example, Asuna fights gigantic tentacle monsters, whilst within Neptune, all the heroines struggle against slim monsters, etc.
SAO attempts to pass itself off as having a serious plotline with an added romance aspect, while Neptune is much more lighthearted. However, both series share a similar atmosphere in a game-inspired, futuristic universe, and characters in both series are often seen fighting off monsters and other enemies with swords, spells, etc.
