I don't really like doing other peoples' list or criteria. My most-wanteds are basically these 3.
1. Crash Bandicoot
2. Spyro
3. Master Chief
Cloud, Sora and Banjo used to be on this list with Spyro not quite making the top 5 then and Sephiroth being what I considered a pipedream. For real I use to rationalize Sephiroth as a boss battle before I considered him for a playable fighter despite how much I wanted it to happen. Sakurai legitimately blew my mind with that reveal and I appreciate his willingness to pursue the character.
There are other characters I'd like of course. Waluigi, Skull Kid, Dr. Robotnik, Tails, Knuckles, Scorpion, Terra, Kefka, Sukapon, a Warcraft rep, Zagreus, Conker, King Boo, and the like but they're not really the big ones I really really want. I'd just really be excited for any of them but in a passive way. I'm legitimately asking for my listed 3 still.
If EiH returned and I got these 3 I legitimately would feel wrong to ask for any more characters, especially since I only really want 3rd-party stuff. I guess at that point I'd just have a top 5 or so of most-interesteds rather than most-wanteds haha.
