In game advertisements has been something that has been expected to happen for the last...20 years
Yeah... this isn't anything new. Sims3 did this with the prius car ingame. Honestly I'm okay with this, its free and you don't have to redeem or build it if you don't want to. They could have included it automatically and forced you to see nissan charging stations popping up everywhere in your commercial areas.
The thing is if in game advertisements were always in that form in The Sims 3 it would be perfectly fine. In The Sims 3 the car was just a car, it didn't come with billboards, it didn't play any advertisements, it was just a really good car that you could buy that had an interesting description if you chose to read it. Heck I would have absolutely NO PROBLEM with The sims always having real life cars that weren't DLC because they way it was done was so unintrusive that I wouldn't mind one bit if I saw a Toyota in The Sims 4.
It is when it is a bit more intrusive with billboards showing advertisements that it gets annoying. Though since this still isn't forced I have no issue, it is not really well done but whatever, so long as they don't force the charging station then I'll leave this as "Stupid stuff you can download".
Heck the Kitkatbar sodapop machines in Theme Hospital were weird. What were they drinking kitkat bars?
