I've been playing--and sucking at--roguelikes for years, and I wanted to chime in to suggest "Caves of Qud" for anyone that likes this genre. It's a modern roguelike that's still in active development with a really imaginative universe: "The game features a mix between a post-apocalyptic and a fantasy setting, and is heavily inspired by the pen-and-paper role-playing game Gamma World and Dungeons & Dragons."
