First off, you are being kind of a jerk. Obviously I meant days of ruin and simply put in a typo. In Days of ruin, you assign the CO to a unit and it is implied the CO is in that unit's "squad". Regardless, within the game the CO acts as your avatar and it is also implied that they are commanding the army alongside you. For Sami to direct infantry/tank/aircrafts would be analogous to what she is doing in the games (regardless of whether she IS or ISN'T on the battlefield).
Let me start by saying that it wasn't my intention to come off as so abrasive. For some reason I was frustrated while typing my post. I don't want to backpedal on any of my points, but I do want to apologize for my tone. Second, I should also state that I've only played Dual Strike (a friend gave it to me and I had never heard of the series before), and despite loving the game I never actually beat it because I'm really bad at it. And it's been a long, long time since I played it. Anyways the point I'm trying to make is that I didn't know the COs were ever actually on the battlefield. However, since that is true, I would prefer that she summon units the same size as her rather than the assist trophy style. Although I realize that would be a great deal more work.
Furthermore, if you are arguing that creative liberties are being used if we were to make Sami command troops, well, I'd argue that some creative liberties are obviously better than others. If we were to give Charizard a lazer, that would be a worse creative liberty (out of the fact that its totally unrelated to the franchise) than if we gave Mario a coin up b. And just like making Olimar the size of Squirtle is a creative liberty we will permit, having little army infantry, tanks, and air planes might be a creative liberty that stands in the realm of possibility in game design.
Actually Charizard can learn Hyper Beam with a TM... lol. But I know that's not your point, I'm just being silly.
Having never played a Pikmin game and knowing almost nothing about the series, I don't know how big Olimar is supposed to be. But from what little I've seen, he's still of the same relative scale to the Pikmin who walk with him. I see where you're coming from but the idea still doesn't appeal to me.
In my opinion, " translating [marth/ike/roy's] combat style from a turn-based, limited interface to that of an action game" by using hte source material for inspiration is a lot like having infantries/tanks/aircrafts conjured in front of Sami, for the purpose of her directing/controlling them.
I don't agree with this. The counterattack is something the FE guys can actually do. To me, the idea of Sami conjuring miniature soldiers is more like if Marth had to stop after each attack and wait for all of his opponents to make a move: something that only makes sense considering the interface of the game he came from. I know that isn't a very good example though.
By comparison, I labeled your example of the creative liberties taken with starfox/cfalcon as "bad" because there is obviously no alternative for those characters EXCEPT to take massive creative liberties. I mean, how the **** else could fox/cfalcon exist without being in their ships. And clearly, there isn't an overtly obvious way to put them on the stage in an arwing/racing ship without it being a game play/design nightmare.
My point, though, is that Smash created full-fledged movesets for them that have nothing to do with racing/dogfighting (not even callbacks), and they are great characters. I feel that this is viable for Sami.
Alternatively, I'm providing a feasible, logical, and fun way to play Sami with the "stage control" you want while making legitimate references to her games (that by and large involve her commanding troops--NOT fighting with rocket launchers and whatever generic war themed items that are typically associated with a "snake clone").
I'm not sure what you mean by "stage control", actually. What I want is a character who would fight like a military officer likely would if she were on the battlefield instead of commanding troops.
Though I really wish Pichu got the Dr. Mario treatment, though I know why he can't. (Same reason why Toon Link doesn't have a Young Link alt model.)
Also, I think Knuckles is sort of silly and would prefer Ridley/Dark Samus over Knuckles. But Ridley maybe held back because of his Smash 4 chances and I guess Dark Samus isn't interesting enough? I think the only real reason Ridley isn't a shoe in is because Smash 4.
