You know cubeddumbnook, you are progressively becoming annoying the more posts I read by you.
You think you have a point, but you don't. They are called extras for a reason. Half the time they don't even really enhance gameplay. At best you get something like the Tingle Tuner, but even that isn't worth all that much. Animal Crossing gives you all of a boring little island. Mmmm what else. I can download chao into a chao garden, etc.
Point being is that there really isn't all that much you can DO with the connection. Sure it's fun to have the extra incentive, and YES, Nintendo does it to sell more of both system, but it's still a gimmick. That's the defenition of a gimmick - something that isn't necessary, but is sold in order to provide an incentive for less than the amount you paid for it. In other words, you spend 10 (cable) + 70 (GBA) = 80 for some things maybe worth 5 bucks.
You were the same guy that complained about mini games. Well same idea here. Shutup. The outcomes of the mini games basically aren't worth the trouble half the time. A 200 rupee? Who cares. I can get that amount in far less time it takes to A) get a treasure map, B) sail to the area, and C) line it up and get the treasure.
I'll say this. I think you do have a point. I just think it's a very weak one, and you're raging against a machine without any real point.
If, and when, Nintendo makes a game that REQUIRES it - and I hear the GC Pokemon does - then you'll have a point. So in the future you might. Until then, just shut up. I'm tired of your whining. If you want access to all the features, then shut up and bite the bullet.
It's all economics and marketing. If Nintendo realizes they can sell an additional 100K GBA's because of the hookup feature, they'd be stupid to NOT take advantage of it. There's also the fact that Nintendo needs the gimmick to really differentiate themselves. But both of these points could be debated and discussed far more than I am doing right now, so I'd rather leave this topic here.
