Is minecraft modded or vanilla? It's hella different. If nothing changed for last few years(didnt play last versions of minecraft for like 5 years, but played modded 1.70), minecraft uses single-threaded process, that means CPU doesnt need to have that many cores in it(2 is enough), but the ram has to differ between 4 to 8 gb(if you want multiple things running, lean to 8GB).
I am not familiar with overwatch system requirements, but i guess its heavier than minecraft on the GPU, so if it's an issue you can check the requirements yourself.
I cant decide for you but i can offer some questions you should consider asking yourself when choosing:
1.do you need a laptop with a battery that lasts for long time unplugged from the tap?(if you want to play games with it unplugged, you need strong battery or even couple of them precharged)
2.do you want a balance of power comsumption and performance or you're fine if performance is better at a price of poor battery lifetime and laptop being warm?
3.check where laptop ports are and if you are ok with their place in the casing(usb and other ones)
4.do you want your laptop hardware to be supported(bios, drivers)? or you dont mind not updating your windows and other software
5.are you ok with price/quality ratio? are you overpaying for the brand? what are the alternatives?
6.how much time you have to decide?
7.what can you do to specify your needs more?(if you want to get a quality answer)
8.where the grid that lets the air in and out is located in the laptop casing? is it comfortable to use? (these parts need free access to air and dont have to be blocked or laptop will have problems cooling)
[Sorry for the questions being in kind of random order]
And a question from me: what is a pen input? You mean touchpad?(i guess no, but i asked anyway) Or the laptop has to have touchscreen display? Or does it have to be compatible with external drawing device?
