Beyond the social and emotional benefits of these kind of games, most of the games that you mentioned also help work on motor coordination, both fine motor skills and gross motor skills. For kids in the 3 to 8 age group, these motor skills are very important for success and self esteem, both in and out of school. Improved fine motor coordination will help with writing and drawing. Hopscotch and Twister can help with balance, coordination and flexibility.
The other benefit to keep in mind is that these games are relatively inexpensive ways to promote skills while encouraging kids to have fun. They are a lot cheaper than video games!
