I am a controller snob
So many videogames have bad controls.
In some cases I’m more or less ok with it. In an RTS, it’s more or less not an issue; precision and reaction time are not critical factors.
But if you are making a fighting game or a shooter, for the love of God, make sure your controls are responsive.
I’ve been frustrated with DOA4 recently because there’s a delay between when I hit a button and when my character reacts. In a fighting game that’s pretty unacceptable. The only game I’ve played with perfect response is Counter-Strike (Half-Life).
It makes all the difference in the world to me.
