Vampire: The Masquerade — Night Road

This is just all around a really good game, it's easy to see why it won for "Best Gameplay" in a recent poll on r/hostedgames. Set in the World of Darkness, the lore is rich, the stats interesting, and the stakes (hehe) high, with plenty of story-appropriate moral choices along the way. You play as a low-tier vampire courier tasked with delivering a series of packages/messages to various powerful vampires, each of which seems to want to use you for their own purposes. You'll have to make hard choices to pursue your own goals while staying alive and not angering the local powers too much.

My main warning with this game though is that it does lean more heavily into the gameplay side of things than many other ChoiceScript IFs, which won't be for everyone. Casual players may be frustrated by having to think so much about how to spend money and allocate stat points, and how to best manage hunger and injuries. It's easy to fail miserably on many of the quests in your first playthrough, and if you're not already familiar with the World of Darkness, there are a lot of factions and concepts to keep track of. Even so the prose is clear and evocative and the characters interesting which makes it a good read even through some of the failures. Overall though I might not recommend this for new IF players unless I know they are into WoD or other RPGs already, or don't mind a few failures along the way.
