Shin Megami Tensei

First-person dungeon RPG set in Tokyo after a demon invasion triggers a nuclear response. You wake up thirty years later in a wasteland controlled by two factions: the Order of Messiah (backing YHVH) and the Ring of Gaea (backing Lucifer). Your choices determine which side you support or if you reject both. Combat is turn-based, but you can talk to demons mid-battle to recruit them instead of fighting. The fusion system lets you merge two or three demons into stronger allies. Exploration happens from a first-person perspective as you navigate the ruined city. The story hinges on alignment—your decisions lock you into different endings based on whether you lean lawful, chaotic, or neutral. It's methodical and systems-heavy, built for players who want consequence-driven RPGs.
