"In terms of actual price of $70 or $80, for really great games, I think it will still be a steal in terms of the amount of entertainment that the top games, top quality games bring to people compared to other form of entertainment."
I actually don't entirely disagree, problem is that I've yet to play a game that was actually good enough to be worth $70-80.
Even the highest rated games of all time have flaws that every video game has. The tech simply isn't advanced enough yet to justify the cost, not until we have games that are designed so well that you can do practically anything in them that you could do in real life. That means we have to move past things like invisible walls, awkward conversations with NPCs that don't flow like a real conversation would, buildings that can't be entered, short walls that can't be climbed over, etc. (e: I've been around since the 3rd gen of consoles, and I can't believe that we still don't have the kind of games that I've been dreaming of since childhood.)
Furthermore, if your game has microtransactions, you can shut the fuck up. They generate so much income, that Free to Play is a sustainable business model. I am of the opinion that any game that has loot box mechanics, gambling, etc. should always be free.
