can i marry and have kids with other players sim?

This is for the player who thought that you have to buy the heirloom trophy. If you receive a request from another player and accept that request, your sim that is leaving leaves you an heirloom trophy. You will receive one for letting your sim go

Yes, but to have someone else’s Sim move in with you, you have to send them a move-in request. If they accept you take control of their Sim. If you receive a move-in request and accept then you lose that Sim. I’m not sure if it ever notifies you if they turn down your request.

The other player invited me to move in with her. But it requires me to leave an heirloom. Getting an heirloom is too pricy. I need to buy heirloom ticket that costs 450 cash in exchange of 100 heirloom ticket. Heirloom requires 40 heirloom tickets. I only have 3 hierloom tickets and 106 cash. This is so hard

When u marry another player's sim they will automatically move in with you.

U should buy the wedding stuff and then click on them

You can propose at 6 lvl

One of my sims has 2 children with another players sim, who also just turned into an elder. They are not married but their relationship is at full level 10 and I am waiting for the option to propose, hopefully I am able to do so.

Probably yes, you can.
