I will be very dissapointed if there won't be a new part by 2024. The age of a game is a non-factor to me, I just don't like ts4, so in 2024 it will be 14 years since the last life simulator I enjoy. Even elder scrolls come out more often lol.
I am looking forward to competition, but paralives is nothing but promises, so I don't really believe in it. Sims exist for 20 years and there are still no competition. At this point I'm starting to believe consipary theories about EA working to make it this way. I believe and wait for paradox but as far as I'm aware that will be a somewhat difftent genre.
I really love the first three parts and they still entertain me, so I don't really need a new part, but I can't help dreaming how cool could it be, how much could be implemented with current technology and experience if done properly and with soul (because there are more than enough people who are ready to give more than enough money so that's not an issue). Honestly, I would gladly purchase even a good mix of first three parts with bug fixes - screw actual innovations.
