Are laptops good for gaming?

Are laptops good for gaming? I heard that playing games on laptops would defect to the performance of the laptop… Is it true?

Laptops can be good for gaming, however generally for a laptop to be able to play modern games you sacrifice quite a bit of poratability - i.e gaming laptops are heavier and have lower battery life than ‘normal’ laptops, plus they are a lot more difficult to upgrade vs a gaming PC. Gaming laptops tend to be more expensive than their desktop counterparts also.
