Fun
Theres new rewards to get and everything comes with the MAXIS humor that comes with nearly every game it makes. MAXIS has even made the sims part of the game. You get 4-5 sims you can place in your city and you can watch them as they move up in your city. You can check anything from what they work as to how old they are. There's a few heads from the sims 1 to chose fromand they aren't very varied but ah well,it'snot a major part of the game.
The graphics are quite good but it would be better if in god mode you could add snow to your mountains or add deserts or make your cliffs look more rockier then just plain grass.The day/night option can add many beautiful views of your city whether it be your thriving metropolis at night or a train crossing a bridge over a deep river in the sunset.
It will seem hard to resist building everything at once at the start but you just have to learn to wait and build neccessary things when they are neccessary.
All I would change would be the graphics to make them better, to add a more varied choice of buildings, bridges and to see lots of different building instead of the same old over and over again and perhaps make it a bit easier but thats about it.
Theres not much else to say except this is a really deep game that will be played for hours on end.
