I mean, I don't HATE it.

I think it's a perfectly good smartphone game. I don't tend to be able to rationalize buying many smartphone games, just because I carry a PSP/DS/3DS everywhere.

It's not that I don't get why smartphone users like it, I don't get why Nintendo and Sony are worried about something like this.

It's fine, but it's nothing whatsoever like Peace Walker or SFIV 3D or Pokemon Black, etc. This is, in no way, a replacement for those. How are people seeing these experiences as competitive?
