These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Moral Event Horizon: While many characters end up crossing the line, none go further than Catalina Thorne - at least, according to the Agency's propaganda, which is actually completely false. Collecting all the audio logs reveals that Catalina is actually one of the most outright heroic characters in the series thus far.
Sequelitis: Okay, so Crackdown 2 was nearly identical to its predecessor, but it left out a few tiny details that are missed. The city is less-pretty now due to damage and a different rendering engine. There are no cool briefing videos on local targets in the area. Worst of all, Agency vehicles do not transform when you get into them!
Hop into the back of a pickup truck as it begins to cross a bridge. Shoot the tires out of passing vehicles with a sniper rifle, trying to get them to swerve off the side of the bridge. When the pickup reaches the end of the bridge, hop out and catch a truck heading in the opposite direction. Repeat until out of ammo.
Unfortunate Implications: It's not as bad as it could have been, but Crackdown's goals basically amount to this: "Kill the Latinos. Okay, now kill the Eastern Europeans. Okay, now kill the Asians." When you learn the big twist the implications become explicit statements.
