You are ultimately responsible for every interaction when you play a fighting game. If a move doesn't work the way you expect and it causes you to lose, the game is not to blame for this, you are.

Fighting games are deterministic, and virtually every interaction could be researched or studied if you had unlimited time. If your anti-air got stuffed by a certain move, you could have known this would happen in advance.

Now, I don't expect every interaction to be fully known by every player... that is pretty unreasonable. And I recognize that some interactions in FGs can be frustrating. But the game is never at fault for your own lack of knowledge. You need to learn and adjust going forward.

You can get put in a dangerous trap where everything that doesn't go according to your plan is never your fault. This will both stunt your growth as a FG player and make you needlessly hate on a game. It is exhausting to be around and I have seen many good players fall for it.

Some new replies to this thread have been discussing bugs and other such "unintentional" effects, and I would recommend that you read my educational article on famous bugs in fighting games and how they have impacted our favorite games: https://ki.infil.net/w01-bugs.html
