They're free, there's no risks involved, you have more control over the content you want to see, and it can get pretty creative. If you absolutely want sex games, go with video game that support mods such as The Elder Scroll V: Skyrim where a player-created framework called SexLab exists that has spawned hundreds of various sex-related mods (nudity, prostitution, bdsm, etc), or The Sims 4 which also has a framework for sex-related mods as well. This isn't so say that these are necessarily scams, BUT.they're very likely to be of extremely low quality and you're most likely to be charged for every little action as soon as you've entered your CC.
I would never trust those 'gay sex games' shown in these ads, even more so if they ask for a credit card upfront.
