I remember how FE never came out in the true way to me through Smash, and me just hearing how it is a SRPG was scaring me away from it. After trying FE7 and clearing it though, I was beyond frustrated and disappointed on how just little justice Smash did to the series aside from music and perhaps the characters.
At the moment though I'm glad they're pulling more things from the series, like the Colosseum, Arena Ferox, the spells for Robin, and so forth. But I think there could be more done? For example:
- We could have different class NPCs fighting in a war if we ever get another Castle Siege-esque stage. Pegasus Knights, Horsemen (paladins, great knights, you know), Wyvern Riders, Mannaketes/Shapeshifters (My term to the animal transformer tribes in the series), etc.
- ITEMS... Come on. We could have had like, a weapon pulled from FE instead another Kid Icarus Uprising-weapon. Unless Sakurai just doesn't know what to do with those weapons (I can't blame him but... YOU'RE CREATIVE FELLA... enough biasement...)
Also all the tools and powerups from the series (Tikis Tear, maybe the Skills themselves like Luna giving you more power to break shields, etc. Or that could be a weapon too, like in the games!)
- Lyn could use more familiars in the Assist League. Micaiah? Black Knight? Heck, Jugdral-lords? I'd go for Micaiah and Black Knight though. Also maybe Lissa or one of the Big Bads in FEA?
You get me. More stuff to make people GET what FE's about. Not about "Is Marth or Roy/Ike/Robin/Lucina in this game", while staying forever clueless about it's theme and perhaps gameplay-like nature.
