I want to make a cocktail system in my games however I have a few questions.
The Title Question, Are Non-Alcoholic cocktails allowed, how ambiguous can it be (Can I just name the drinks without specifying if its cola, juice etc.).
Can I use irl shakers and shot glasses.
Can the cocktails have alcohol-Like effects (Dizzyness, Blurring, Nausea etc.).
Context matters a lot to moderation so the more clear you are about the beverage and its design, the better it is for appropriateness. Juice and ingredient mixes aren’t so much the problem as it is anything that can be perceived as alcoholism or drunkenness.
I’m not an authoritative source on policy so don’t use my word as fact but a shaker or mixer is a lot more appropriate sans context as it can be used for both alcoholic and non-alcoholic drinks but you probably aren’t going to fly anywhere with a shot glass so consider different cup designs.
“Alcohol-like effects” seems to defeat the purpose of your question which poses this as alcoholism without directly stating its alcoholism. Alcohol and references to it as well as depictions of drunkenness are explicitly outlawed in the community guidelines, so throw that idea out.
If you’re looking for any authoritative interpretation of rules it might be best to reach out to support or developer engagement for an answer.
