The Stern Insider Connected Achievements are cool, but some of the games don't have many/any interesting achievements. Mostly just normal stuff you'd get in the course of "100%ing" the game.

The MXV skillshots are cool, as are the Stranger Things achievements where each mode has a special hard way to beat it. But there aren't many more examples than that. Deadpool has an achievement for tilting away 5 mil in bonus, which is amusing. Maybe I'm being too harsh, I guess there are some interesting achievements.

Pinball isn't really flexible enough to have achievements that are as interesting and specific as the ones in some video games, but there's still potential for improvement.

Here are my suggestions, some of which may need tweaking:
Jurassic Park:
Get three DNA combos in the first 90 seconds of your game.
Deadpool:
Get three or more Teamups in a single battle. (You can do more than one in a battle, right?)

You can also post boring ideas for achievements in this thread, if you really want to.
