As others have noted, set & setting are hugely important as well as staying away from other intoxicants during the experience (unless you are experienced with LSD or in the care of someone to guide you through the trip). It's not surprising that the combination of the video game and weed would have this effect. I personally can't even look at a screen during a trip, it looks too cartoonish and just beyond uninteresting to me.

My personal rules for any LSD trip are: be in the company of others you feel comfortable being sober with (as in no drugs, not even weed or alcohol), be in a safe place or near a safe place you can get back to without much issue if things get overwhelming, relaxing music, lots of fresh fruit on hand. Oh, and make sure anyone you're with is not on any sort of anti-depressant. I've seen some bad mixes with SSRIs and psychedelics (primarily DMT).

You should be ready to go introspective during your trip. If things get overwhelming, lay down, focus on your breath, and remember you're tripping and that you will sober up in a few hours. Let yourself cry if you need to. The worst experiences come when you try to fight it.
