Tecmo Stackers, released September 1, 1997 by Tecmo for the Playstation. I'm a huge fan of puzzle games, so I had to grab this one when it first released. Addictive gameplay similar to Puyo Poyo with chains similar to Super Puzzle Fighter II Turbo, I was hooked immediately. Lots of fun playing 2-player head-to-head. I still play this one occasionally.
