This framework is for B2B Providers (Gaming Affiliates and Support Service Providers) who supply systems/games to a Gaming System Administrator (GSA), the actual operator. As a developer building games, you would most likely be a Game Content Provider (GCP) or Game Aggregator (GA) — not the operator itself. To run a full online casino, you'd also need to either become an accredited GSA (separate framework) or partner with one.
You cannot legally just "build and launch" — every system, every game, every parameter change requires prior PAGCOR approval.
