crusade.gg seems to be down. Do you have a live page where all these games can be previewed? $350 sounds extremely cheap for the games being offered. Do you also provide the payment integrations/casino manager's dashboard for this amount? Are you selling the source code or you would just deploy an instance with all the provided games?

Regardless, starting your own casino in a few minutes seems to clickbaity of a title as it is way more complicated than that even if one goes for a proper White Label/Turnkey solutions.
