B/c in the long run, if the dude actually likes PC games and wants to run them properly (i.e. at 30fps or 60fps and at a worthwhile resolution to his screen's ratio) - well, b/c he has a not-so-hot laptop and wants to actually play some PC games with it, he's going to have to either ditch PC gaming (b/c it's too pricey) or just get a better one.
If he thinks PC gaming sucks from that experience w/ a weak rig - well, that's what happens when you actually have a weak system; it's a crap-shoot. If he goes for something better - that's gonna be more $ spent, instead of just buying something decent from the get-go; and he has a better chance of maybe liking what PC gaming can do. Unfortunately, that's just the way this works.
Getting older or weaker systems to run PC games properly, whether old or new, just can be a royal pain-in-the-ass. With things like trying low-end solutions, having issues w/ old games on newer OS's and hardware/software, maybe even just trying to get things to sync properly and/or get them to even run worth a damn - eh, it can really suck and be a crapshoot. And this is me literally speaking from experience here, as I have before bought a weak laptop and tried to run some older stuff on it. Seriously, Intel integrated graphics cards are pretty much be a waste of time; and it's not really worth that hassle most of the time, TBH.
If we're talking worthwhile older FPS's to run on some Intel integrated graphics cards - Old-school classic Doom games (Doom 1, Doom 2, Final Doom) and Quake stuff (i.e. Quake 1 & 2) run really well with some Source Ports. Hotline Miami 1 also ran quite well for me.
