Could you give me a bit more than a no maybe a use or reason to keep your laptop as it doesn't get use
As indicated by the other posters, if you want to play Legend of Zelda: Breath of the Wild, you don't need a second opinion - you need $469 for a Nintendo Switch and the game. While there are attempts at making 'Zelda' playable on PC, most of them either don't work or are borderline illegal.
As for selling your laptop: If you can find someone willing to pay $1,500 for a 2015 Alienware, then by all means do that! With $1,000 left you can choose between several light-weight 'café cruisers' (aka ultrabooks) that are likely to be much more useable to you than a 17" gaming rig.
