What is DLC vs an expansion has become somewhat blurry. There was StarCraft BroodWar that was really an entire separate game to the point of launching them separately at the menu. Now things like Rimworld (which I play far too much of) have these expansion/plugins that add new mechanics and features but don’t create a separate game in their own right.
I actually read an article recently about 20 years of Oblivion horse armor or some such. They made an interesting point that a lot of the acceptance of micro buys came from online games letting you show off your new gear to the masses.
As ready as they’ll ever be, which probably isn’t all that ready in absolute terms…
