I only see this trend leading me away to specific games and not the triple A dollar machine.
To be honest, the games I currently enjoy most could probably last me years, and yes since most are unfinished that probably helps lol
DayZ -
I'll be playing this for years to come, no extra money over the price of the game
7 Days to Die -
same as above
Escape from Tarkov -
they mention dlc at some point in the future but for the next couple of years - at the very least - I'll be playing this without spending an extra penny
Star Citizen -
in theory I could spend more money to get another ship, but it's not needed and buying one in-game with in-game money is kind of the point of having a career etc etc so yeah no extra spending necessary
