I'm curious what you guys have to say about this. Are there any games you consider perfect? Can a game even be perfect?
My example of a perfect game is always Portal 1. Portal 2 has more going on, but in 1 there just isn't anything to shave off. From start to end, there is nothing I'd change about the game. It's short, infinitely replayable, great pacing. I like Portal 2 a lot in concept, in concept it should be a perfect sequel, but it just doesn't keep the extreme tightness of the original game.
Half life Alyx for me. I've played hundreds of games in every genre and nothing has ever given me such a visceral emotional reaction as that game. From beginning to end I was drawn into the experience so much I forgot how to use my hands in real life.
Genuinely felt like the guy at the end of The Witness. Kept trying to reload my fork at dinner.
