Ignoring the lack of updates if the game is buggy, games back then were also more focused on quality and make gamers replay the game with unlockable features based on skills, not money. I can't count the number of times I played Metal Gear Solid games over and over to unlock new features playing the hardest difficulty and with handicap features, and also to find Easter eggs. Speaking of Easter eggs, you'd lose a number of hours exploring every nook and cranny finding them!
I remember when volvo invented lootboxes to make tf2 free to play instead of selling a $60 "AAA" title with a battlepass and lootboxes included.
They should have made the patent free to use as long as the game was free to play, like they did with the seat belt patent
If memory serves, Valve got the idea for the loot boxes from Korean free to play games. As far as I know though, they did invent the battle pass with Dota 2.
