Smashboard's 1st Sole Survivor
All they really have to do is release new character gameplay. We got K Rool/Dark Samus/Chrom gameplay randomly, that was great. Yet we never got Simon/Richter gameplay...I agree in regards to the drip-feed, I don't think that needs to be done.
Just releasing the character trailers when the blog updates is enough though.
Heck, even veteran gameplay (not the ones from the demo) would be great. A free for all with like, Luigi, Duck Hunt, Shulk, and Yoshi would be freaking hype cause we could nitpick and analyse all the little changes for a least a week. Release a gameplay video every few days, boom, drought over without releasing too much .
Right now, the hype train is kind of decreasing for me with radio silence. We got Isabelle who IMO wasn't hype for me and that's it in like, 2-3 months? The last piece of new information we got was Ash-Greninja...via text.
Tl;Dr, release gameplay videos of unseen characters, whether they be newcomers or vets...in any capacity.
