Exactly. There were a ton of these in the 90s, like StarCraft Brood War, Warcraft II: Beyond the Dark Portal, and my personal favorite Lords of the Realm II: Seige Pack.
Even today, there are plenty of great examples, like the new DLC for Factorio, Space Age. Good DLC isn’t a problem, MTX and DLC acting like MTX are the real problems.
Wait, they weren’t already? I guess I already assumed that many (most?) black hats were white hats in the daytime. You gotta get that knowledge from somewhere…
