I understand that Hyrule Warriors has practically revealed they have to offer as of now, but are you really not going to buy the game simply because there's nothing else being revealed? I spoiled myself for Hyrule Warriors because I'm really excited for the game and though most if not all of the information has been revealed, it's not going to drop my sense of excitement mainly because I still need to wait for the game to be localized so I can read the English text (as I can't read Japanese but do know the gist of what is going on story-wise). That's like saying when the Japanese release for Smash 4 3DS reveals everything, I should not be excited simply because I wanted more or because there's nothing else to reveal. It's one thing to know what's is revealed for a game and another to actually have a first-hand experience. My excitement for Smash 4 will not drop even when the full roster is revealed, because that would be nonsensical from me to not be excited for a series I love simply because the roster was revealed and that's. If you wanted to stay excited, don't force yourself to be spoiled, simple as that. What's the point of watching Japanese streams if you are going complain that there's nothing left to be revealed. I've watched Japanese streams left and right (e.g. GameXplain) and I'm even more excited for the game because of how fun and energetic the game looks, especially gameplay wise.
Honestly most people have this mentality that once everything is revealed, they lose excitement for a game they wanted to try out or play. Which makes absolutely no sense if it is a game that people have wanting for a long time. This is a hypothetical situation, but does it really make sense that if everything about OmegaRuby & AlphaSapphire were to be revealed before its release and the people who have been wanting this since as early as 2010 to just not be excited anymore and potentially not buy the one game they have been begging to happen? To actually lose excitement because everything about a game has been revealed just makes no sense. It makes the person sound and look selfish because there's nothing to be excited about. It's a Gen III remake using Gen VI's engine. You don't want to see a 3D Hoenn, Hoenn at night, new Mega Evolutions, Primal Devolutions, updated contests, artwork redesigns, a free Shiny Beldum with the Mega Stone as soon as open the game, and so much more all because there's nothing to be revealed left and you wanted more? If that's the case, then you either 1. were never really interested in the game or 2. should have known better to not have been spoiled as this is the internet were news travels in seconds. There's people that don't know everything revealed for Smash 4 and/or OmegaRuby & AlphaSapphire because they chose to not be spoiled. I'm not going to drop my pre-orders for Smash 4 just because I knew the roster a month before I got my copy of the game. I chose to spoil myself because I am very excited for Smash 4 and the more that is revealed, the more I want the game. Even if everything were to be revealed by September 13, I am still going to be excited because now I know what to expect and focus on the characters that I need to study and analysis to better fit my playstyle.
