Alright. Here's an interesting thought (since there is little in the way of news or leaks). I was thinking about what the future of DLC could look like and realized something about my "most wanted" list, namely that there are two categories of desire for me.
The first category is a general want. This want extends beyond personal experience and preference, absorbing part of the fan base's desires. These are those characters that I want in the game not necessarily because I personally like the character or have played their game, but because of what they'll bring to Smash (like Simon and Sonic were). In some cases, I actually don't like their franchise! However, I can't deny the impact or importance of the addition. These include: Crash, Doomguy, Tracer, Travis, and Rayman.
The second category is hype. It's those characters that, if added, I can see myself jumping off of my couch for (like Banjo and Kazooie, Shulk, and Mega Man). These are the characters I have actually been requesting and/or campaigning for. Their franchises are ones I indulge in because they are incredible, making their addition to Smash the stuff of dreams for me. These are those characters I main because of their inherent value, regardless of their moveset. These include: Scorpion, Isaac, Geno, Dovahkiin, Steve, and the impossible Master Chief.
The cool thing is I'll be happy if either of these lists have anyone get in, but the hype list brings more overall joy. Looking at your wants, who fits into which category for you?
