What's wrong with that? It has! Try playing the first Sims game and see how far you get!
For one, You are assuming its hard for everyone because it was hard for you. For The Sims challenge is pretty subjective I think. I've heard A LOT of different opinions on what people think of the difficult in each iteration, all vary wildly. For me, I played the first game for years and still do occasionally, and I never found it to be that difficult at all. I can't say I have found any of The Sims games challenging or difficult. To me, 4 doesn't feel any easier than any of the others, just different.
but let's be real here, the point of my statement was that they replaced challenge with creativity because generally that will appeal more to women!
Do you have facts to back that up? That women only play games with low difficulty and that are more for creativity? It seems like its just an assumption based only on your own personal opinion and experience. I can agree with them going more in the creativity and freedom direction, I don't agree it is only to appeal to more women.
The sims when it first came out, had a much larger female fan base than male. I remember seeing stats on the numbers back in the early 2000s with numbers like 70-75%% female player base. Over the years though, that number has balanced out and I've seen some polls in much more recent years with an almost even 50/50 split between men and women (I believe this was back in 2013 or early 2014). So if we are saying they are decreasing the difficulty to attract more people, it seems its mainly attracting more men.
I know that I for one spend much more time in character creators than my male friends, which arguably the sims is!
100% anecdotal and doesn't mean anything. I can completely counter it with my own, because I know guys who spend WAAAAY more time in game CCs and making individual sims than any of the girls I know. Neither of these statements matter though, because again, anecdotal and no basis in actual fact.
In the end, the entire point and the problem people are having is that you are just making a very large generalization based on no hard truths or facts, you are saying "Well yea The Sims is for women, because it isn't difficult!" the implication being that women only want easy games, and men only want challenging games, that the easy games are always "girl games", and hard games are always "boy games". It just perpetuates the stereotype and makes people like the OP feel bad and out of place.
