What is the big deal about twins. Anyway the best thing to do is keep your sims peped up with "maxmotives" then lock them with 'motivedecay off' Then you can do anything day and night with out getting tired or going to the bathroom or anything. I used that to get my sims maxed out on their skills. Then you can pick a career and go all the way quick cause you know everything and your in a gret mood all the time. The other one that is great is "motherlode" gotta use that one all the time. Don't you just love this game. I do wish there was an x-rated version to it though. Wouldn't that be cool for those of us over 18?
