I prefer to listen to dialogue if it is well voiced. I read and skip the voice if it’s bad.

Good voice acting is extremely impactful if done good. Remember Irenicus? Or the Barbarian Chieftain in IWD 1 add-on.. in modern games it’s Eder and Durance in PoE. Those performances are game defining. Also, in general, remember Mass Effect, RDR2, Witcher 3 etc etc. so many games would be totally different without the genius voice acting behind the characters.

On the other hand, bad/cringe voice acting can absolutely ruin the experience…
