An often overlapping problem is designers splitting a game into "expansions" that they sell at launch as part of the KS. "Here's the core game, it's everything you need to play! Not too expensive right? ....but here's an expansion with some new races. And another with a new hero. And another with some new missions. They're totally optional, but if you don't back them now you'll never ever find them in retail. How much do you trust that we've put all the good bits in the core?"

Awaken Realms has been one of the worst offenders with this (both fake stretch goals and fake expansions) but their newest KS (Nemesis Lockdown) actually abandoned all that for timed feature announcements.

Hopefully the start of a trend.
