On January 9 (local time), entering the North Hall entrance of Las Vegas Convention Center (LVCC) where CES 2025 is being held, the red words "LOTTE INNOVATION" caught my eye on the ceiling. That is also the reason I came to North Hall. Lotte Innovate metaverse platform "Caliburse" at this CES 2025 presented ultra-realistic metaverse content and powerful metaverse platform based on these 3D contents, suggesting the direction the future metaverse should take. The Lotte Innovate booth at Las Vegas Convention Center North Hall was crowded with visitors wanting to experience ultra-realistic content. Caliburse is providing completely different immersion from existing simple virtual worlds, receiving great response from visitors. The booth experience: visitors donned VR headsets to enter the Caliburse ultra-realistic environment -- the Unreal Engine 5 photorealistic rendering immediately distinguishes the experience from typical metaverse demonstrations; the LVCC North Hall location is typically for automotive and smart home technology -- Lotte Innovate presence there rather than in the startup/digital media halls signals positioning as a serious technology platform rather than a niche entertainment product. The "dungeon" metaphor in the headline: Caliburse at CES felt like entering a dungeon -- a space that captures you completely once you enter; the immersive quality that makes time feel suspended; the combination of technical achievement (Unreal Engine 5 fidelity) and entertainment content (Tomorrowland collaboration, virtual concerts) creates a compelling demonstration of what metaverse can be when quality is not compromised. The global metaverse direction Caliburse is suggesting: rather than the stripped-down blocky aesthetics of Roblox or the uncanny avatar environments of early Meta Horizon, Caliburse demonstrates photorealistic quality as the baseline expectation; as VR hardware improves (Apple Vision Pro, Meta Quest 3 Pro), the quality bar Caliburse is setting will become more accessible; Lotte positioning at CES is a statement that Korean companies will compete for the premium metaverse market globally, not just domestically.
