Dungeons and Dragons Online (PC)
You can’t really have a “games like D&D” list without Dungeons & Dragons Online. DDO, for short, is developed by Wizards of the Coast, which of course created the tabletop game. So this is pretty much as close as you can get without purchasing a dice set or tracking down a Dungeon Master to narrate and create your journey.
DDO launched back in February of 2006 and is only for PC players. But don’t let the age of the game or its graphics fool you. DDO receives regular updates, one of its recent big ones includes the Dragonborn race which tabletop players have been utilizing for quite some time now. You can download and play DDO from its official site.
