Uh no that was sarcasm(which is hard to get across via text, and besides, you can't fix perfection(more sarcasm)), so you're saying they should just cancel SO4(assuming it is SO4) and remake SO2?
Or that Metroid Prime isn't drastically different from Super Metroid?
I do see your point though, which is really why I'm not a big fan of Nintendo's, I wish they'd alter the formula more often, change it up, only title of Nintendo(first party) I enjoy is Zelda really, but because I grew up with it(along with FF/DQ/etc), and I still have fun playing them.
I was stoked for DQIX back when they unveiled it, because the battle system was an action based battle system(I was kinda shocked at first they'd change it, cause DQ is as traditional as all get out), but now I'll admit I've lost some interest, because recently new scans of the game have been released by SE, and it looks like it's back to a turn based battle system, which disappoints me to say the least. I guess they got a bad reception from pretty much all of Japan(they love them some DQ) about the action based battle system, so they reverted back. Not to say I won't enjoy it, just not as much as I could have.
Back on topic(sorta), I'd be interested to see a SO MMO, if they did it right it could be rather fun, too bad that probably won't be this announcement coming up.
