This is one of many reasons I hate Apple products. Imagine if you couldn't play Pokemon Black and White on your Phat DS, people would rage...
Well it's a bit different. It's more comparable to like cramming in the concept of console succession (like DS to 3DS, not DS to DS Lite) in a much shorter time. More recent iDevices are more powerful than older ones and thus have games that can only work on them.
I'm not really defending it since it's basically a shitty ploy to essentially keep people buying their products and at high prices (unlike other consoles, whose prices are drastically lower than they were at launch when their successor comes out), but it's the way it is.
I would love more 2nd gen iPod support though although I've been flirting with getting a 4th gen device. You can find them for sub-$200 if you get one for smaller memory. Odds are I'll keep my 2nd gen for music or switch over to my PSP Go for that, 8GB is enough for games.
