Just bought the 3DS... and I am truly shocked. The 3D is really outstanding. People complaining that it hurts your eyes, give it time. Seriously, I felt the same way. If you look very carefully at whats actually on the screen and don't pay attention to anything around you, you will become accustomed to it. I love the 3D.
I haven't bought any games yet, but I'll be picking up Pilot Wings tomorrow. HOWEVER, I have one MAJOR complaint.
First let me just say, those of you who know me KNOW that I'm never one to complain, especially on the release of something. But one detail with this is absolutely bothering me.
DS games look AWFUL on the 3DS. I mean... I can't even play White. You can say I'm over-dramatizing it... it is playable, but the resolution just looks horrendous. I will never play a DS game on the 3DS, it bothers me that much. I'd even go as far to say that if you are completely happy with your DS, stick with it until huge games come out on the 3DS. Really, it's that bad.
Yes, there's a "resolution fix", which is actually worse. While the look of DS games is just pitiful, the console really is innovative. I have no doubt that Sony and even Microsoft will follow in Nintendo's footsteps.
Anyway, that's my two cents. Feel free to ask my questions about the 3DS if you really are curious about something.
