It is a game that is often considerd to be girly and dumb, but is quite addictive.
The original version, has no point other than goals that you may set for yourself, where as the version on consoles, or the Sims 2, has a point to the game, and in game goals for you to meet, to create that oh so perfect life.
Oh man I am so tired, I was up all nigth playing to sims again!
It's fun to start off on, but after a few hours, you get bored and want to quit. After awhile, it's very hard to keep your SIM happy, and it's hard to balance their basic needs.
For example: If your character is too tired, they won't do anything but sleep. Their hunger level goes down and you have to wake them up to get them to eat so they won't die. However, they fall asleep at the table, and leave the stove on. So you have to pick up after them. You forget about the stove and your kitchen catches fire, and you end up having to call the fire department while your Sim either runs around in panic or tries to put out the fire.
Also, if they don't make it to the bathroom in time, they'll go right where they're standing, so you have to pick that up too. If you don't take good enough care of them, ominous music plays and the Grim Reaper comes. You can plead with him, and if you plead enough, he won't kill you. Watch out though, if you choose to die, make sure you're in your yard or something, because a gravestone is left where you die, and you can't ever move it or get rid of it. So don't die in your kitchen or bedroom or some place like that.
All in all, it's like taking care of a bunch of drunks. Sometimes I think the kids on the game are smarter than the adults. They're also easier to care for, since they go to school for most of the day, come home, eat, and then go to bed.
Oh, and another thing. Your character's social level cannot drop too low, or they'll become depressed and lethargic, lying in bed all day or crying every two steps they take. Every other level will drop too.
It's a very finicky game, and you'll end up spending most of your time just trying to keep the levels high enough so your Sim doesn't die.
It is a good game if you want to pass the time though.
