Some quick impressions:
- the 3D at the highest/enhanced settings is pretty strong but surprisingly pleasing to they eyes. I occasionally noticed some ghosting, but I guess that's expected with a game like that. If you like the 3D on the 3DS you will really like this one I think.
- the graphics itself are amazing, but we already knew that.
- the controls without the CPP seem absolutely fine to the point where I'm not sure what the CPP even does. I'll get the CPP essentially for free, so I will definitely try it out, but I almost expect to play this game without it.
- I think 3rd person shooting is the way to go here, even though I didn't even try the 1st person mode, mainly because it just seems wrong to me and always looked wrong when I saw it in videos.
- the bottom screen is used for weapon/item shortcuts and a map. Both seem pretty convenient, even though you can just access most items with the digi pad.
- not a lot of ammunition, but still just enough.
- I personally like the scanning feature. Not sure if everyone will agree on that.
