Or preferably: don’t care about the game at all until it releases. Ignore previews or alpha demos, beta footage, gameplay trailers/teasers, etc. That way you don’t build up hype that has a big chance to disappoint you. Take the game for what it is at release and either like it then or not.
Typically I get easily distracted or bored during movies. The only exception in recent years was Oppenheimer. It had such a fantastic pacing that the three hours rushed by and I didn’t pick up my phone even once. It was incredible.
