Err... I think that playing PC games online is different from Consoles... it may be "more advanced" but it's not even close to main-stream.
You guys talk about monthly fees, but do you realize that a person who wants to play games online is liable to pay 10x as much $$$$ just to get STARTED on the PC. Is it 10x the quality? Maybe, but most aren't willing to pay that much, period.
To me, PC online gaming might as well never have existed, because the most I have ever done with it is play a game of pool or spades. PC online gaming may be great, and I may be missing out, but eh, I'm not about to risk $3000+ to find out
I say more power to MS and Sony (and Sega), for online gaming they revolutionized it for me... They recreated Multi-player games, period.
As for this topic, I feel that GCN-GBA Link up has yet to move past the level of "waste of technology" in my book. Nothing shown from what I have seen could make a GBA owner want a GCN, or a GCN owner want a GBA... the only people who will be using this crap are people who just happen to have both.
