I find it a little alarming that they have stated there will be a continuation of Sims 4 packs for some time to come.
As much as I have loved this game, I think it reached its summit with CL (or before) and has been rapidly going downwards ever since. Slapping more content into the mess will only accelerate that slide down to the bottom. They need to stabilise it before trying to go further.
They overdid it with TS3 and then just abandoned it, leaving us with the ability to disable some packs we had paid money for in order to improve performance. I'm fully expecting a repeat of that scenario and, if that's the case, I will not be buying into TS5 to start all over again on what will eventually become an abandoned buggy mess.
