Hum... I like The Sims...
Natrina: First let me congratulate you: Gratz you finaly got the 2 red stars!!!
For a start (or just to keep it simple) the things could be made like that (the sims way or another simple one), but later, for players who know how to make models, textures and scripts, the things could be made like this, but every house made in the second way should be seen by the admins, \'coz they may contain bugs, that may cause the game to get... what\'s the word... piffed... or may contain a virus.
