Runescape is not "predatory gambling", not even the couple of Belgium government officials in their own petty island said it is.
BTW, the video game industry is exposing the dirty laundry of the Belgium Gambling Commission. The BGC is in hot water as they pretty much admitted they leaked reports and harbor their own equally "guilty" Belgium companies like the ones who operate Pokemon games.

"According to Verbruggen, the civil servants of the BGC leaked the report to the press without consulting the commission's elected representatives. Additionally, he said the BGC didn't consult with stakeholders in the games industry at any point while compiling the report."
"Under the current definition, Verbruggen noted that even a school raffle is technically illegal, as are trading card games such as Pokémon. However, there are certain exemptions under Belgian law. It's worth noting that Cartmundi, one of the largest playing card manufacturers in the world, which also makes cards for Pokémon and Hasbro, is a Belgian firm."
The video game industry is not lobbying these so-called "governments". They are going to the expose their unethical and unfair, if not unlawful and corruptive practice to their own real governments and the whole world.
