Most roleplaying games either totally railroad the player, like the Final Fantasy series, or they let the player do what they please in an open world, like the Fallout or Elder Scrolls series.
Though seemingly as different as can be both types of RPGs, and pretty much all video games with roleplaying elements, have some rather comical elements in common.
There's the party member who dies in the storyline despite having been resurrected dozens of times in battle, the armor that turns into a bikini when equipped on a female character, and the sewer full of hidden treasures.
Because every stinky sewer must be full of hidden gems, right?
