I've been a mostly physical guy for years, trading in the games when I am done (for SP games) and rebuying digitally if I want the game "forever".
This fall however, at least in the USA, the corner has really turned to heavily favor digital. Black Friday / CyberMonday this year had a ton of sales on very recent games, and the prices were pretty much equivalent between physical and digital. Trade in values for used games have also dropped hard, while before it was easy to get $40-45 for a new game at gamestop/best buy now the max is around $35 in the first 30 days and it drops hard fast after that.
Plus I find myself wanting fewer and fewer games every year. It was easy to skip Battlefield 5 and Fallout 76 this year, they both didn't look great and both dropped to 50% within a week of release. Thats insane.
I expect the tide to continue in digitals favor going forward, there will still be games I buy physically (SP games) to trade but at this point the real decision is whether to buy a game at launch or wait a few days or weeks for a sale.
