I won't really write much, just starting off by saying I put more than 400 hrs in NGB, around 100 in NGS and another 130 hrs in NGS2 ( which was disappointing btw). As you can see a big NG fan here and I have been waiting for too long to play NG3 and here I am struggling to finish it for the first time.
CHEAP, CHEAP, CHEAP + Poor design choices = NG3:RE ... challenge is great, but when you can't do anything about it, it becomes boring, everything is random and neither the controls nor the design helps you to fight back.
I can write millions of words to describe how frastrated I am and disappointed in this game but I won't, i wasted enough time already on the game.
One thing is for sure, the first ninja gaiden was just a coincidence, team ninja isn't a good developer for action adventure games and the original ninja gaiden was just pure luck.
P.S
Just to be fair, the game manages to introduce some interesting move sets for the weapons, but you will rarely use these long cool combos in actual combat but still they fooled me at first, may be that's why I was hyped for the game.
Verdict: Don't buy unless you can cope with frustration.
