TBH, I am loving how SSBU is being shown off. I love how they shown off every veteran and didn't add any as DLC because one of my least fave things about SSB4 is the amount of veterans that were announced as DLC. but without this being an SSB4 rant I'll actually speak about how I feel about Smash Ultimate.
It makes me glad that if they ever do add DLC (which is very possible), they would ALL have to be newcomers as there are no leftover veterans to add as DLC.
As for Ideas, none of my character ideas are super likely but I'd like to see Birdo, Micaiah and Lightning (even though I don't anticipate a second Final Fantasy character). As for modes, I really want Smash Run (forget Smash Tour, it felt out of place) because it was such a fun mode especially because it had a lot of enemies from different series. If they don't do Smash Run then do a Melee styled adventure mode with levels like Mushroom Kingdom and Hyrule's Underground Maze
For this, I'd pick Link, Pichu, Snake, Ike and Bowser
