Rogue: Genesia has some of the most fun builds to power spiral out on, up there with Nova Drift for a "I have enough rolls to start stacking fire...BURN THEM ALL!" experience. It also has a concept I'd like to see utilized more, in Defense Shredding, which is an attack stat that permanently reduces your opponent's defense by that amount each attack. It makes faster/multiple attacks vs strong opponents a viable strategy rather than always needing high single shot/crit damage to deal with armored enemies, and opens up numerous build and mob possibilities. It's also on the prettier side for roguelites, and does a fantastic job of breaking down all your stats and how they're calculated, so you can immediately see the effect of new items/traits and how they affect your final damage or defense.
