I haven’t finished Spec Ops: The Line, but I recommend that. It looks like your average American propaganda third person shooter but the story is actually super interesting and thought provoking. Looking at https://howlongtobeat.com/, it’s 6 hours for the main story.
You could do like me, play lightweight games on a normal laptop and heavy games on a desktop.
Also ASUS these days has a very bad track record, even the ROG Ally has some issues like the buttons getting stuck and the battery.
