EO4 dun have club nintendo point 

Not every title has it.

It's like a very good game of random titles with codes. KH 3D, has it. Call of Duty Black Ops II WiiU, nope.

All US Nintendo titles, yes, it has it. Asian ones, nope.

It's a weird thing. Really.

Preemptive strike and enemy weakness is the only way to make the game easiest.
Talking to demon.. I dunno, it's not that hard but not easy too, better luck answering them. I sacrifices everything for them.

I got 2 death so far.. I heard this game magic is everything. So I focus my character more to magic, Speed and Luck and a little Dex and Str stats.

Nope. I played Nocturne, Soul Hackers, Strange Journey etc..
In IV don't have moon phase system like previous series... Maybe that's why?
Like I said, in IV it's not easy but also not hard so far from what I'm playing right now... it's all depend on luck.

I talk about SMT IV not other game
