Aside from graphics others difference include :
- less enemies in NGS2.( still over 1k kills per clear , for me that's more than enough).
- Normal mode in NGS2 is easier than normal mode in NG2.
Bosses tend to have more hp in NGS2.
On master ninja difficulty some sections of NGS2 are actually harder than in NG2 due to the lack of bow UT in NGS2.
- less cheesy off screen enemies throwing projectiles at you ( noone is going to complain about this).
- Global difference in difficulty between NGS2 and NG2 in Master Ninja isn't huge ( trash easier because less, bosses harder because more hp).
- Some of the co-op missions will give a challenge to anyone complaining about the game being too easy ( go beat Ultimate Ninja missions 1-3 Gutbuster and then come back and tell us the game is for casuals...)
PS : Who buys Ninja Gaiden and plays easy mode, seriously....
As for why the game isn't selling more, PS3 owners aren't stupid. Give them a game one year after the 360 release and they won't flock to it. It's Bioshock all over again. If you want a game to sell well on a console, don't release it one year after releasing it on another console...
PS3-Xbox360 gap : 1.5 millions and going up in PS3 favor !
PS3-Wii gap : 20 millions and going down !
