I actually quite like that new Kirby game for the DS where you have to draw lines, and I'm 18...
The Wi, though simple is the same. It'd be quite fun I imagine to use that controller!
I personally like the PSP as well (haven't got one mind, and probably won't buy one. Handheld, though it interests me somewhat, since 2D games are more widely spread, I don't personally use them). Though, everyone likes the new Sonic Rush. I don't. I still think it goes way too far from the originals.
I think its movie support is useless though on those discs (since who would buy them when you can buy a DVD with extras).
EMULATION (Best part in my eyes)
Anyhow, the best part about the PSP in my eyes is the emulation support for a wide range of consoles which are downloadable, More and more will come along.
Its powerful enough to I believe to support a wide range of consoles, including the N64, which has been proven somewhat, even though the N64 is rather hard to emulate due to a few factors (If you've played a PC one, you'll know why).
I also think with a bit of work, it could run Saturn games for instance, though this takes even more processing power (might be a bit too much).
I tihnk the only downside with the PSP is the memory sticks which are, lets face it, expensive for only a small amount of data. 1GB sticks are I believe too expensive, and for a person who might want quite alot of games on 1 stick...
Yeah, megadrive, snes roms would be fine on a 1GB, but when it comes to N64, Playstation, etc, your going to need more room.
A lovely little attachment for a mini hard drive (possibly 4gb) wouldn't go amiss, if there was some way of making it fit somewhere.
