depends on the game and the number of Move controllers you have
ok, you can play with two people at once, with two controllers. if you don't have two controllers, you're screwed. big-time... No
Yep
Four controllers can be connected either wired or wirelessly to one console. Each console can only support up to four or fewer controllers at one time.
You can connect up to 7 controllers. And if people want to use the PlayStation Move while playing, (using 2 controllers) you can have 3 people using it, and have 1 person using the original controller, or 2 people using PlayStation Move and 2 people using original controllers, and etc.
2 ELECTRONS in one orbital. (An electron can only be in one orbital at once)
preferrably, 3, but if you have to get ALL your dogs walked at once, as many as you can
You should play it, of course! Also remember to register it on Club Nintendo for Coins.
About once a month
You can use a controller hub to ad more but i think the limit is 4.
You cannot have six children at once in the Sims 3, the maximum number the game will allow is three. If you want sextuplets, try searching the internet for a mod that will let you increase this number.
Yes, the console is built in order to accommodate group games. More than two might require additional controllers, since I think only two come with the console, but at least one demo slip shows four people playing at once.
