NetHack and Dungeon Crawl Stone Soup are really good rougelikes. They’re also really complicated. Brogue goes back to the original Rogue and takes things in a slightly different direction, almost a minimalist one. Every monster type is unique and must be fought differently. There are no classes, only the equipment you find and the way you use it. Lighting and different terrain types can be taken advantage of (either by yourself, or the enemies). There are Indiana Jones style traps. There are organic dungeon designs with lakes, and pools of lava, and rickety bridges between cliffs.
The control scheme has also been simplified, This is a good thing. One key can be used to quaff potions, read scrolls, zap wands, etc. You can also use a mouse for movement, combat, and getting more info on symbols.
It’s also really pretty. The lighting system casts various hues on things with fire and sunlight, water ripples, and fire pulses. And it’s still rendered using text and ascii symbols.
A good first roguelike, but enjoyable for fans of the genre in general, too.
