Actually, the opposite is true.
Not only were the trailers out there, but Universe was playable at public events before it was cancelled. I got a taste of it myself.
I find it sad that you people complain about how much you want Legends 3 and put effort into only to then laugh in someone else's face when they do they same for something they want.
You are terrible hypocritical people.
First of all, all of my negativity was directed at the game, not the fans. I'm laughing at a piece of programming, not at a group of people.
Second, I'll gladly be the hypocritical prick if that's what it takes to strike down the flawed logic of "the only reason anyone cares about Legends 3 is because it was cancelled". Universe is the control group that proves it false.
Third, no it isn't the same. Nobody opened up development of Universe to the public, and granted full coverage of the initial greenlight meeting, only to cancel it without warning behind closed doors five months later. Nobody ever said that the reception of a trial version of Universe would decide the game's fate and then pulled said trial before it could be received, after specifically asking the target audience to be patient for it following a nonspecific delay.
And perhaps most importantly: Mega Man Universe was nothing new. It had the exact same strengths and weaknesses of Powered Up, which failed, and applied them to Mega Man 2, which Capcom had already spent the last two Classic installments dry-humping.
Make no mistake, despite my being unimpressed I still would have bought Universe if it came out. And I'd have loved to see it overturn my expectations the way MM10 did. But the bottom line is that Universe had a lot to prove, made a playable appearance, and through that playable appearance, proved nothing. And all of that was before Inafune left; I'm not sure anyone besides him understood what exactly the game was supposed to be in the first place. I can't in good conscience tell Capcom that they were wrong to cancel it.
Absolutely none of that is applicable to Legends 3. The devs were psyched and on-track, the response from the extremely few who did play it was positive, and a full-featured 3D adventure could have gone a long way to establishing Mega Man as a relevant force in modern gaming, as opposed to the NES relic that he's otherwise been easily dismissed as ever since the nostalgic shock of MM9 wore off. Capcom destroyed it all because it was a "dead brand" fueling a too-scary-open community. Bull. [parasitic bomb].
As desperately as I want the game, there's more to it than that. They were wrong to cancel it, and doing so was a detriment to the franchise. I happen to also really want to play Rockman Online, but I wouldn't throw the same weight behind it.
