Lesser chance of prom event and/or becoming a prom royalty and more for The Sims 3 Generations
I am not really back from the dead but I decided to repost a tuning mod of mine because I figured you will quite like it.
This tuning mod that will alter the prom experience for your sim teens comes with some flavors. Please choose only one because multiple versions of this mod will conflict with each other.
Proms are special: lowers the overall chance of proms to 0.05 (0.5 by default) and the cooldown to 4 sim weeks (instead of 2 weeks).
Lower prom royalty chance: Makes the weight of your teen sims friends 0.05 instead of 5 to become a prom royalty.
Proms are special + lower prom royalty chance: A combination of "Proms are Special" and "lower prom royalty" flavor. (So you really don't need to try install both versions!)
Every 3 days is prom: The prom tuning mod from Devilgurl (who deleted their Mod the Sims account so I provide it here) that makes the prom chance to 100% and every 3 sims days.
Every 3 days is prom + lower prom royalty: A combination of Devilgurls prom tuning mod and lower prom royalty" flavor.
Non american mode (Experimental): That will "remove" proms by turning the base chance of the event to 0.
These mods only work with The Sims 3 Generations installed so there is a prom in the first place.
Have fun!
