Game: TwinBee Taisen Puzzle Dama
Release date: 1994
I wouldn't go so far as to say it's one of gaming's greatest atrocities, but I'd definitely say it's a bit of a shame that the Taisen Puzzle Dama series--think Puyo Puyo with bells instead of blobs and subtly different rules--has yet to make its way to the States. Three Taisen Puzzle Dama games were released for the PlayStation in Japan--including one that features characters from Konami's Tokimeki Memorial series and one that's called Susume! Taisen Puzzle Dama (sorry, I have no idea what "susume" means)--in the mid-1990s, with this TwinBee-themed iteration being the best of the bunch, in my somewhat uneducated opinion. (Although I own all three of the aforementioned games, I've spent quite a bit more time with TwinBee Taisen Puzzle Dama than its successors.) That said, I wouldn't suggest running out and buying a copy unless you're a huge puzzler and/or TwinBee fan, as it's been bested by a number of its peers (namely Puyo Puyo and Super Puzzle Fighter II Turbo).
