Pricing is not tied to cost.

A game costs what you will pay for it, not how much it costs to produce. If you’re willing to pay $70 for Madden 23, it will cost $70 on DVD, digital download or 289,348 floppy discs.

DLC is awesome. Microtransactions suck.

If you want to release a semi-sequel or expansion to an existing game, I am 100% down for that.

Absent knowing what to your kids want to play, I’d suggest Sony. They have a better library of games (IMO, obviously) and that’s what’s important in a console.
