You will either love it or hate it. There doesn't seem to be a middle ground with Tetris Attack. I personally fell in love with it while standing at a Toys R Us and playing the demo unit (they had it set to reset the console after 5 minutes). It became a "Time Attack" for me to see how far I could get in that 5 minutes.
I was addicted enough that I stopped in and played a good half hour every evening after work before heading home. I would have just bought a copy but I had long since gave away my Super Nintendo by this time - a family member had a birthday and they were wanting a Super Nintendo but their parents couldn't afford one. I gave mine to them with 10+ games because it felt like the right thing to do. Last I heard they still have it and the games, and about 90 more they have bought over the years since then. I believe their kids play it now. Talk about getting your money's worth. Lol.
