My my... you're never wrong are you?
Look, to be clear, you're totally getting off-topic. I'm saying I understand Sims 4 fans, explain why TS3 failed to appeal to me, and say that despite not being a TS4 fan, I understand them plainly nontheless. Simple. I didn't call the game you like a bad game.
1-Rest are game facts. Bianca Rubble to the art gallery, any explanation? Followed by Kat Missonni, how about that? Well that's called player stalking. Pescado knows the game better than both of us. If he identifies this behaviour and mods it, that's cause it exists. Your Harley/Rei reference... really didn't make a strong case for you. Also, no matter how many I send home, others come, relentlessly, up until 10PM in regular neighbourhoods. Cause they're all in relation with Rei? How about Florita Hernandez? Oh Yes! Because the man she flirts with is married with a bookworm :/
2-No, not at all. Sometimes Loners isolate, sometimes not. They do what they feel regardless of their environement. Even if there is a stranger in the living-room, if Lola Belle wants to play the piano, she will, even if Kai and Moxie are outside. TS2 shy sims tend to use items close to sims they like (maybe to an extreme). Again that's a preference due to experience. Nothing more. I find them cute, period.
3-I do. Brigid steele serving in her singer outfit. Why did they put her in that career, nobody knows. And guess what, she defaults to that instead of the club regular outfit.
4-Quote the line when I say I'm the only person in the world. You praise zombies. I don't like them. That's all I'm saying. I never involved anybody else. I'm just shocked we can't turn them down with a single click. Instead, just no full moon. A shame, I like the light of the full moon.
5-If you prefer that's on you. I say that it's more appealing to me when two sims don't NECESSARELY feel the same towards one another. In TS3, if a sim likes another for 85 points, the other also does. Cassandra LTR towards Darren Dreamer is 69. Darren's is 85. I prefer it that way. I don't say it's the ultimate. Also for TS3 I hoped for a LTR meter, it never came, a shame for me.
Those are amongst the things that made TS3 less enjoyeable than TS2 for me. As such, again, all that is to say, if one love TS4 getting to a new game in TS5 may make them lose more than they gain. You love TS3, that's fine, I never said it was a bad game, nor did I try to convince you it sucks. Just taking an example on how it failed to keep my interest, just as TS5 could do for TS4 afficionados. This is called empathy.
Anyways I'm done here. This post asks a good question which divides the community, that's the topic and so it should stay. If you have questions on TS3 that you don't really seem to know so well, ask me in private. I'd be more than eager to enlighten you, rookie.
