What is New Maximiliania? It is my special neighbourhood (started in 2008) in the game "The Sims 2", where each and every Maxis-made family, single Sim or student has found a home, no matter whether they were originally placed in Pleasantview, Strangetown, Veronaville, Belladonna Cove, Bluewater Village, etc., and no matter with what expansion pack they were added to our games.The houses and community lots in this neighbourhood are all the Maxis-made originals, too.
New Maximiliania (or New Max, as it is affectionately called by its inhabitants) is played entirely without CC and no hacks, and the only cheats I use are the ones to put furniture diagonally or place two pictures on the same bit of wall etc.
Each household is played for one Sim-week in alphabetical order of their surnames.
All Maxis-made Sims get a fair chance at reaching their lifetime want. Upon their age-transition from child to teenager, I decide each Sim's aspiration by lot. If they have a 3-bolt-attraction for another Sim, I try to get the couple together; I usually let them get married only if one of them has that want, and children will only come if they are key to fulfilling a lifetime want - or a male Sim is abducted by Aliens.
If you want to create your own Maxis-families neighbourhood, please do NOT just go and move the families into the family bin and then place them in their new surroundings. That way, you are going to destroy the whole neighbourhood after some time, because a large number of double character files is going to be created.
Instead, please check out http://www.sims2wiki.info/wiki.php?title=Game_Help:Moving_Sims for detailed instructions of what to do.
To my knowledge, you can also download a clean and ready-to-play Maxis-families neighbourhood on MTS2.
You are very welcome to read what those Maxis-Sims we all know so well are up to in my game, and I'll be happy to read your comments and answer your questions, should you have any :-)
