Fighting games are full of these.
>Omen of Sorrow
Released in 2019 for PS4 and the Tencent Games Store, Omen of Sorrow is a fighting game based on public domain characters from classic European literature like Dracula, Dr. Jekyll, Archangel Michael, etc. The game also features a mechanic called "blessed." Once your character is blessed, he can temporarily cancel special moves into special moves with total freedom. The intention is that you build up to being blessed over the course of a round or game, then use it as a finishing blow against your opponent. Unfortunately, because there are no restrictions this means three things:
1) There are many infinites for every character.
2) The infinites are boring and easy, and do very little damage.
3) The timer for blessed lasts way too long, so you can be stuck in a combo for a very long time.
It sounds neat on paper, but as soon as I saw the werewolf character do a simple punch > punch > downward claw > upward claw and loop the downward and upward claws infinitely, I knew there was a problem. I normally like mechanics that give players total freedom, like Street Fighter Alpha 2's custom combo system, but the devs in OoS fumbled it.
