So if Rex somehow did make it in what would his stage and 8 songs be (not counting the 3 songs already in Ultimate)?
For his stage I'd go with Leftheria since it'd be a great way to show off the Cloud Sea and maybe some of the other titans far in the background.
For his songs:
I made a list myself a while back, but I couldn't contain it to just 5, 8, or even 10.. I think I did 15. Many of them were battle themes cuz a number of the battle themes are great for the smash setting.
As I recall, mine was broken into 4 area themes, 6 battle themes, and 5 cinematic themes...
- Gormott (day)
- Mor Ardain (day)
- Tantal (day)
- Yggdrasil (probably remix)
- Incoming!
- Monster Surprised You
- You Will Recall Our Names
- Bringer of Chaos
- Giga Rosa
- Power of Jin
- Counterattack
- Crossing Swords
- Irritation (probably remix)
- Over the Sinful Entreaty (probably remix)
- The Decision (probably remix)
Naturally.. there's many many many more songs I love but I didn't put them in my list either because even though they are great it's hard to imagine them being remixed "hard" enough to fit a fighting game since they're more mood pieces, or they're maybe spoilery or less often heard. Not to mention, I originally made the list to be 10 but I'd already outgrown my self imposed list size so I didn't want it to get too out of hand.
Anyways, as a for instance, Walking with You is one of my favorite songs in the whole game but it's hard to imagine it as a stage theme. Likewise, the main theme's most "big" version is probably Yggdrasil, but the sounds of the main theme's melody should be in the mix somehow. Also, of the semi-spoilery songs.. the final battle theme "After Hope and Despair", which.. damn that piano and the mood of that piece would certainly be epic... but I passed on it since it's end game and heard once. Like I said, songs that should be picked should at least be recognizable as having happened a few times in the game. That said.. not sure I exactly followed my own rules and kinda just went with my gut on most of them under the restriction that I wasn't just gonna start listing them all~
I used to have a playlist of this stuff on Youtube.. but half of it disappeared when Mixz Highwind took down their channel due to pressure from Nintendo.
Edit: Also, want to add...
Uraya theme is beautiful and I'd love a remix just as an excuse to get it in there. Leftheria is also beautiful and would fit as a more subdued theme for a stage or they could try to remix that too. Oh, and more Torna themes would be sweet. I made my list a while back before I beat Torna. The battle theme is very nice but also I love the Torna themes.. tho they are more meandering and less dynamic in the way of a theme good for Smashing to. But I really liked the area music in Torna, yeah.
