Log Horizon

Log Horizon is an isekai anime (with a strong focus on strategy, politics, and world-building rather than pure action or combat) set in the MMORPG world of Elder Tale.

One day, after a major game update, over 30,000 Japanese players (including hundreds of thousands worldwide) suddenly find themselves trapped inside the game as their avatars, unable to log out. What was once a virtual fantasy world has become their new, very real reality—complete with game mechanics like levels, classes, skills, respawns after death, and more.

The story follows Shiroe, a highly intelligent but socially awkward veteran player and master strategist (often called the "Enchanter of the Glasses" or similar nicknames). He teams up with his old friend Naotsugu (a tanky guardian) and the petite but deadly assassin Akatsuki to navigate this new world.

Unlike many "trapped in a game" stories that focus heavily on battles or escaping, Log Horizon dives deep into:

• Rebuilding society among the chaotic players
• Forming guilds and political alliances (especially in the player hub city of Akihabara)
• Economics, governance, diplomacy with the game's native NPCs ("People of the Land")
• Strategic problem-solving and large-scale planning

Shiroe forms the Log Horizon guild and works to bring order, stability, and progress to the trapped adventurers while uncovering the mysteries of their situation.

It's known for its thoughtful take on MMO mechanics turned real life, with a lot of dialogue, scheming, and civilization-building rather than constant fights.

If you're into smart protagonists, guild management, and isekai with brains over brawn, it's a classic!
