@Salsuero I agree, they are garbage. Avatars and achievements have no value whatsoever, except for looks.
Which is exactly what the Graveyard is. Difference is, it takes up a giant space in your city for that garbage, while avatars and achievements take up no space whatsoever.
Sure, Graveyard gives happiness too, but that's it. Way too big for what it offers. So, like I said, build it for looks. Still a disappointment to me though. Which sucks, cause it looks so cool. It should have gotten some sort of update. Something else added besides it's happiness.
Just my opinion of course. I just wish it was better.
