Laptops tend to have a higher build quality than a desktop, thus they are far more portable than lugging around a desktop to do what we affectionately referred to "lan parties" of the late 90's and early 2000's.
Once WiFi became a standard thing (eg Wireless B around 2004) on a laptop that didn't require an expansion card, the idea of gaming on a laptop took off. I had a "gaming" laptop in 2004, I ran the FFXI benchmark on it and... well I wasn't going to play it on it. In fact No MMORPG produced during the 2000's was actually capable of being played on a laptop unless it had a dedicated nVidia or ATI part, and even still, the parts picked by the OEM's were only a fraction of the power of the desktop. What you bought in a $1000 laptop was equal to a $300 desktop.
Up until relatively recently (and by recent, I mean nVidia Geforce GTX 7xx parts and later) hybrid graphics were not even a consideration, and only available on really pricey business workstations. As of the Geforce 10 series (eg 1050 Ti, to 1080 Ti) the desktop parts and laptop parts are now equal. So any laptop purchased in the last 2 years that was built as a "gaming" laptop is equal or better than a desktop under most conditions.
A laptop maxes out around 300 watts. An equal desktop is around 800 watts. If you do not have the luxury of buying a $2000 laptop with a Quadro M4000 (aka GTX 980) or better, the desktop is cheaper, but not portable. All gaming laptops are more like "portable desktops" and are not battery efficient, with a battery that typically tops out at 90 minutes, where as you can get like 12 hours out of a tablet (Eg Microsoft Surface) but it will literately melt if you try to do any long gaming sessions on it.
If you plan to spend hours (eg 4+ hours/day) then you should not use a laptop, as few laptops are designed to run that long at full power, and the noise will certainly tell you that you've overburdened it. If you have pets, or smoke anything, definitely do not use a laptop, as the fans will get clogged very quickly. For everyone else, any laptop with a Geforce 1050 Ti or better is capable of playing the game at 1920x1080 with all settings turned on, and thus the only obstacle is input devices, which laptop keyboards and touchpads tend to be complete rubbish. You're better off playing with a controller.
But I digress, in many cases people are forced to live in cramped conditions at universities, or even just living in cities like New York NY, and Vancouver BC, and space is at a premium. The first thing you get rid of is your gaming rig, because you simply will not have the space for it in a room that can't even fit a queen size bed.
