Every NPC you speak to is fully voiced and has a ton of dialogue and exposition to spit out. What elevates it beyond being another generic D&D plot is the hammy yet entertaining voice-acting. It's also one of those stories where despite there being plenty of soldiers, fighters, wizards, and other warriors hanging about, you're the only competent hero around who can get the job done. It's a classic tale where you keep thinking you've reached the big bad only to discover there's someone even worse beyond them. But as it goes with most RPG stories, there are worse things than random thieves lurking beneath the surface and it's up to you to save the day. Now angry and penniless, you head to the local tavern to gather information on the thieves so you can enact bloody vengeance. They rob you blind and only leave you alive because a couple of passing guards stumble across your concussed body. You're looking to make a name for yourself in the big city, but before you can do anything you're conked on the head by a roaming gang of thieves.
The story of Dark Alliance begins with your plucky hero or heroine arriving at Baldur's Gate.
