I hope the announcement is something else besides The Sims 5. I hate to be negative, but TS5 worries me. I have a bad feeling that when that day does come, it's going to be the end of an era, the end of the single-player sandbox Sims. My intuition is wrong about as often as it is right, so that's what I pin my hopes on for TS5 to continue the tradition of single-player offline simming. I'm a realist, and the people I know who fit their current target demographic love mobile gaming and online multiplayer. On the other hand the majority of the Sims community still prefers the single-player experience. I don't feel like loyal players who've been playing this game for the last decade, two decades in a lot of cases, have a lot of sway in the direction the future takes unfortunately.
I don't care if they make it multiplayer, just include an offline option for the rest of us, the one's that stayed the course and got them to this point. Without us they wouldn't be developing a Sims 5. The franchise could just as easily have died after 2 or 3 without keeping us coming back. I hope loyalty means something.
