Keg Party
Similar to other house parties but with 99% more keg. Memories will be made and shortly be forgotten. Throwing one of these parties is almost guaranteed a bad life decision, but somehow a necessary rite of passage. §100 (Discover University)
...so, as you can see, there are only fifteen events available, but if all you own is the base game then all you have access to is four events. That's it. Just four. There's also an aspect that is rarely discussed about these events in that if you gold star them you unlock items. Sure, most of them won't ever be used, but who doesn't like unlocking everything even if you don't plan on using it?
Do we need more events? Yes! Most certainly. They seem to have forgotten to add events for most of the packs. For example; where's the event for children that should have came with Kids Room Stuff?
Parenthood should have came with an event where you announce to everyone you're having a baby.
Seasons didn't add any events, but it did give us holidays so that one gets a pass.
Get to Work should have an event where you do something with your coworkers.
City Living should have a block party.
Cats & Dogs should have an animal show.
Realm of Magic needs some kind of occult magic seance thingy.
Strangerville could be...what? Okay, that one's hard to figure what kind of event would go well with it. Oh, wait, a military parade or ceremony. Boom.
Jungle Adventure. Hmm. How about a party celebrating that woman who's statue is in the middle of town? Let's do something for her.
Vampires could be a cemetery party where someone gets turned into a vampire.
Dine Out...can you believe this one doesn't come with a single new event? How about opening night when you first open a new restaurant?
Spa day could have an event where a group goes to get pampered. C'mon, we've all heard of people all hitting the spa together one day.
Bowling Night did not come with a new Bowling event. Can you believe that? They forgot to include bowling in their bowling pack.
Movie Hangout also forgot to include hanging out and watching movies with people.
Luxery Party did not come with a new party.
And this was just off the top of my head, I can't believe they didn't think of adding new events. It's like they keep forgetting about events or something.
