Those are the ones that I felt like showing off. There are a couple others that should get mentioned like the X-Men Legends series, Urban Reign, or Mortal Kombat: Shaolin Monks. Dynasty Warriors games have you facing off against tons of opponents and feels a lot like a beat em up. Some of the games based of the Lord of The Rings play a lot like a beat em up with RPG stats. The recent Ninja Turtles series based off the new show, some are like the old school ones. You could even argue for God Of War, Ninja Gaiden, Jet Li: Rise to Honor Gauntlet: Dark Legacy, and similar games to be beat em ups or just lumped into the general "action" genre. Even Diablo style hack & slash games would fit into a subgenre of beat em ups.. Not quite a beat em up the same way that that Turtles In Time is a beat em up, but some of them are closer to the definition than others.
They just don't make beat em ups like they used to though.
