As a fan of the Beat Em' Up genre, this collection strikes the proper balance with each game providing its own unique experience. There is a lack of bonus material and the online multiplayer is a little spotty, but the support for couch co-op is great.
Outside of Final Fight and Captain Commando which I only knew about because of Marvel Vs. Capcom 2 I never heard of any of the other games. That said I love all of them. I was truly missing out on some real gems. Armored Warriors and Battle Circuit are my favorite games in the bundle. Modding your mechs in Armored Warriors with parts from defeated is awesome and I love the over the top nature of Battle Circuit which is not unlike Captain Commando now that I was actually play his game.
