Games that incite emotions, that make ppl get lost in another world.
All sports seem to have this effect. Highly Intellectual or imensely coordinating demanding games too like chess and carromboard. But besides those, what else?
It's quite subjective. Plenty of people find sports and chess to be quite boring and not at all engrossing or emotional. It all depends on what a given person is interested in. Some people get excited by push-your-luck type games with random chance, while others find that pointless and silly. Some people get excited by diplomacy and negotiation games, while others prefer 2-player contests. Etc.
