I haven't played the original Love Letter, but Batman Love Letter (from what I remember, the Robin card is the major variation, but I could be wrong) is a great game to break out for small gatherings. Anyone can play it, and there's enough luck involved that anyone can win a given game.
Star Realms is not as easy, but most people can pick up the basics pretty quickly, and it's one of our favorites. The app is also great!
It requires more setup, but King of Tokyo is easy and fun, too. The main problem with King of Tokyo is that it soon becomes obvious that rolling for points is the best approach most of the time. King of New York fixes this, but new people are more likely to struggle with the rules.
Zombie Dice is almost purely a game you play while doing something else, but it doesn't get much easier, and it's still pretty fun.
