What was the point of the reapers reward

I thought there would be more of a story there simply because it started out like one, and even though I was a bit frustrated when the event bugged out on me for a while, there were many things I did enjoy.

• I had an incentive to use the séance table from the Paranormal set. I've had that set for years and only ever used the CAS and build items but never the actual gameplay. I'll use it more frequently now with one of my new Sims who wants to know everything about ghosts anyway.
• I loved that I could distribute the various tasks. My main household currently consists of the parents and three teenagers. The mum got to do the séance and most interactions with Grim as well as the fishing. The dad usually picked up the newsletters and did some of the cooking, and the oldest of the three teenagers did all the gardening tasks except the one with the Deathflower because the family didn't have the required plants in their garden. Also, I was too lazy and impatient to bother 😁
• Thanks to the event, the dad finally managed to finish part of his current aspiration. Yay!
• I discovered Ghost Night! This is a bit embarrassing because I've been playing this game for quite some time now, but I never was aware there's an actual Ghost Night at the local bars. 
• I never would've bothered to make Ambrosia if it hadn't been for that event simply because those Sims I care about have familiars to protect them from dying. Still, it was fun to do that at least once.
• I finally got the in-game achievement the game gives you when you befriend Grim 😄
• That bike is awesome! And the collection of freezer bunnies looks really nice on top of the piano.

What the event also managed to do for me: It got me in the mood to pre-order and play the new pack, so... mission accomplished, EA, and well played 😁 

One thing that would be a nice asset for future events, other than testing it properly before launching it: make it optional so those who are not interested in it can disable it. 

I didn't finish it, but I'm hoping to be able to clone it with that science machine thing and sell it in my shop. That way whenever i am in need for it my sims can buy it.

I actually haven't been able to play the event since the week before last.  The quests just don't show up in my game any longer, and there doesn't seem to be any way to access them.  So I'm not even sure if I'll get the last two weeks rewards.

The goal is player retention 😅

Lucky you that have made it through!  I appear to have glitches on week 3.  I have a sim with level 10 fishing skill who is catching everything BUT the angelfish.  Fortunately, sim is a spell caster so could get one at the ingredients shop, per one of the steps.  Got a death flower the same way.  The tome says 'read', not 'read intro' and not even a sim that now gets the cue to read it again has completion of that task line.  Between the two that week is not completable so no more progress.

I never finished it and it takes too long just to get the rewards anyway. My idea is if you miss a week: get the rewards for free. Not all of us can finish this awards. 

I have given up trying to do that final week. My sim seems to be unable to get from level 9 to level 10 gourmet cooking and the skill cheat just will not work.
