I really like this compilation. I use the Game B of Tetris (first to 25 with garbage on set to start at level 1 height 0) for a casual level office christmas competition. We get a field of around 16 playing in a knockout format with the final being a best of 3. The Mixed match is a nice idea too but I haven't had much opportunity to try it out. The version of tetris feels a bit old with no hold piece, hard drop or wall kicks but it's still a nice version and it goes down really well in my little office tourney (played through a projector for BIG screen Tetris!!).
