Could you build this?

Partial Real-time multiplayer lobbies and game modes are vibe-codeable, but the 140,000-question bank is a substantial curated data asset that is hard to reproduce with quality and rights clarity.

What it would actually take: The stack is a real-time layer (WebSockets or a managed service such as Pusher/Ably or Supabase Realtime) with a web or mobile front end and a simple nickname-based session model. The hard part is the question corpus: you need to license or source open trivia datasets, dedupe and fact-check them, and tag difficulty and category, which typically means editorial or LLM-assisted pipelines with human review. Scale of concurrent players is manageable with standard hosting.
