There won't actually be a Sims 5 because EA is going to 'disrupt the sequel model' by shoving The Sims 4, Project Rene, and two other games into one 'massive Sims platform'
Yeah as long as they nail it there's going to be a huge reality check for EA.
The issue however is that Korean gamedev culture is MUCH WORSE than western gamedev culture and I am not convinced that their monetisation model will be something the audience will be pleased about.
