All of their games have been that "this really is too short and minimalistic to be flogging at the AAA price point".
The thing is, most of their games are not that short.
Bayonetta and
Bayonetta 2 will take your first playthrough about 10-12 hours on each game.
Vanquish is a 6-9 hours first time.
Metal Gear Rising is a standard 6-8 hours, but the game is all about the combat, and playing the harder modes. Plus, it got DLC support.
Anarchy Reigns unfortunately suffers from the beat both campaigns that are very similar to unlock the true final boss/ending. The game was mainly about the multiplayer, but at least you can play with bots, and the survival mode is super addictive.
LoK was sold at $15,
Transformers Devastation (originally was going to be $30) and
TMNT were sold at $50 (blame Activision on that), but TD is the best of the bunch and the most polished and fun. The loot aspects are fun to an extent, but once you got the weapons you crafted, you might as well almost all of your weapons you acquire each time you beat sections, challenges, or a stage.
Astral Chain is 11-14 hours your first run, and was sold at $60 with little complaints. That game did well on the Switch too.
