Moderate time to learn and play, but nothing crazy
Easy to play, takes 15 minutes or less to learn, not too long to play, but a 10 year old or less might struggle a bit to play.
Games that are fun, and simple enough to play with someone less than 10
These games generally need ~5+ people to play well but are great for large groups
Games that either only play two or are best with two imo
These games take longer to play and require more planning
