New Idea: Co-op Expansion Feature for The Sims

I've been a long time simmer 😉 Over the years and all the expansion packs I've bought, I've always felt there was one thing missing, a co-op feature. I have an idea to make a new expansion pack, that allows this feature. All players must buy this pack and have at least the base game model in order to play in the new co-op feature. Friends can meet up and join in a game session and play how they normally would, but in party mode. The host would be able to select up to a certain amount of friends to co-op with and any additional packs or expansions they want to include, as long as all other party members have those packs. Players would be able to travel together, take on challenges, level up skills, and even decor a shared space together. I know a lot of gamers that would enjoy this new feature, even some that are in other games that offer co-op playing, but lack all the options that sims give. I feel if this was made possible, many others that are in such games would easily come to Sims to play instead, as we're drawn to the co-op and decorating features that Sims provides.
