Meh, I said Mega Man, meaning the ones released in NA and that Battle Network itself is a spin-off (or, to be exact, a spin-off spin-off...>_>).
But, yeah, I'll agree that Mega Man 3 was the best of the original...I thought Legends 2 was slightly better than 1 though because you couldn't just circle all the bosses to defeat them...but the boss in 1 was far more memorable (I don't even remember the boss in 2). "ARE YOU READY!? HRAAAAAAA~!!" That was some scary shit running from that demented fucker. As for the BNs...I'm fairly sure that 3 was the one I hated the most (though the Liberation Mission ones are running a tight race by being so goddamn boring...still haven't gotten through 5)...
