You'll likely need a good graphics card, memory and a good CPU. These mobile devices like Laptops and tablets aren't really designed for heavy game usage, neither to their have the battery for more than a few hours. Tablets have the problem of not having any ability to passively cool down, so when it is being really used, it will get really hot to the touch and that does no good for the components inside.
Unless you got a good gaming laptop and those aren't cheap to get, otherwise i agree with what others are saying, no sims for the weekend.
