"Fine, obscure gems." Part of a periodical series: Great Games You Never Played.
If the words "Fallout" or "Vampire: The Masquerade - Bloodlines" mean anything to you, then you owe it to yourself to play Arcanum: Of Steamworks and Magick Obscura. Developed by Troika Games (the team that made Vampire Bloodlines, and many of the key designers who worked on the original Fallout), Arcanum is a steampunk role-playing game that plays much like the best of the classic RPGs.
Set during an industrial revolution, conflict pervades a society torn between sticking with the history and traditions of magic, and embracing the new wave of "heretical" technology. You play as the lone survivor of an attack on the maiden voyage of the IFS Zephyr. Initially tasked by one of the dying passengers to return a ring to "the boy," you set out on adventure to find out why assassins pursue you and, ultimately, to save the world.
As an RPG, it's among the best ever. There are tons of different ways to customize your character, not the least of which is deciding whether to follow the path of magic or technology. One path has you casting spells of all sorts, and the other has you building equipment from blueprints and fighting with firearms. The game changes and reacts to your decisions in ways that are still unsurpassed in modern games, with a open-world to explore and fulfill quests in a non-linear order. So if you like good RPGs, then you should definitely give this one a shot.
