They don't even deserve that money. I love Ninja Gaiden, I got NG, NG Black, NG Sigma, NG2, NG Sigma 2 and NG3 and I was horribly disappointed with the third. All they did was remove all the weapons, remove the golden scarabs, remove the time trial / 60 enemy fights and remove the shops / weapon upgrades and only added kunai climbing which was a little frustrating at times and the ninja sense thing that guides you to where your going which was heavily annoying.
It just told you where to go even in straight corridors, made the game feel horribly linear since any 2 second distraction to look at the scenery was met with this glaring and annoying text. It was a bad game sadly, good combat system as usual with an NG title but lack lustre compared to previous NG games in every form. Enemies weren't as varied, bosses were boring and less strategy reliant to beat, the level design was more linear, the QTE's didn't add much to the game etc. It was just a sad mess of a shorter game with most of the best features like multiple upgradeable weapons and scarabs to search for left out.
