15. Tekken Card Tournament
Please note that this list does not include Tekken Resolute, or the 1999 title Tekken Card Challenge, as they only released in Japan.
Tekken got transformed into a turn-based card game back in 2013, resulting in Tekken Card Tournament, which also had its own set of physical cards which could be scanned into the game. Each player has a deck of 15 cards and these must be used in order to either Strike your opponent or Block their incoming card attacks. It sounds way more complicated than it really is, but there’s a level of strategy here which was actually pretty darn fun.
The problem is, however, that Card Tournament is a free-to-play game and its microtransactions make getting properly engrossed in the game far more difficult than the overall payout is worth. Add in connection problems and you’ve got a nice idea that lacked the required execution.
