Portable games are pretty much all I've been playing these days. In fact, I have not played a console game yet this year. I've played a few PC games, otherwise it's been all DS/GBA and PSP. I ask this question just to see the responses.
There seems to be an upswing of posts about portable RPG gaming on the RPG boards and some of the "I only play console games, portables are stupid" gamers seem to be getting annoyed with it. I think it's kind of funny.
I don't usually leave my consoles hooked up when I'm not using them, so it's much easier to grab my DS or PSP and start playing it when I come home than to hook up a console and play games.
