So, everyone already saw in the trailers how IQ was improved. The orchestral soundtrack is a great addition also. But my biggest gripes with the graphics in the Wii version are present here as well.
Popup/draw distance is still poor. It might have to do with it being an online game and the area data getting streamed and maybe it's better if you're in Japan and have fast internet. But for me the problem persists.
Also frame rate is still poor. Move the camera and you will painstakenly notice how low the frame rate gets. I got used to it playing the Wii version for over half a year but I really wished they had been able to fix this.
The gamepad is used for communication only. No quick menu selects like in DQIX. This was like a non-brainer so I'm puzzled why it is missing.
The implementation of the software keyboard is also a bit clumsy. But as menues and stuff were improved considerably in terms of convenience since the game first launched I guess they will improve the software keyboard as well. Right now I'd rather keep using my USB plus CC combo (which also has much better battery life).
The home button is disabled, as it was in the Wii version. This means no Miiverse integration (in the beta at least) and no browser to check the hiroba site or other internet while playing DQX.
Photos are taken in HD but on the hiroba site you can only access low res versions. You can still see what version the photos come from, Wii on Wii U has the upscale filters showing and the Wii U version has better IQ noticable even in the lower resolution.
Edit: Removed for now, maybe I'll bring them back later.
Enjoy?
a) Nintendo will compensate people for not being able to play the beta for about a week, given that it was a major draw to people to buy the Black Premium Wii U.
Beta started on Wednesday and the fix was distributed on Friday. That's 3 days at most, hardly a week.
