Nintendogs is something of a tomodachi that you command with voice commands from what I've heard, I've also seen some screens floating around the net and DS sites like DS-Insider. Personally, I think all these titles are great, I haven't seen some of these titles since the SNES days and I've never even seen a few of them on a Nintendo product, only on PS or PS2. This is getting very interesting, I was all for DS before instead of PSP(bc of it's uncommon format, high probability of short battery life, straying away from the gaming industry, etc.), but now Nintendo has just completely amazed me at how seriously they are taking their competition this time around unlike the 64/PS days. Quite amazing.
