Since it seems like Fire is winning out, I'll go ahead and assume that is the primary type, and start thinking about the next step, that is, the secondary typing. I'm pretty much going to assume that we are going to have a secondary type because the game has 8 fully evolved mono Fire types anyway, and I believe originality and creativity should be emphasized. Also, I recognize that is just the primary poll and it hasn't even been decided yet, but since discussion seems to be wavering slightly and it is never a bad idea to think ahead, I figured I might as well do so lol.
I think Mekkah posted that emphasizing creativity would mean that Flying, Fighting, Ground, Rock, Steel, Ghost, Bug, Dark, Dragon and Ice are out of the picture since we have Fire types with those types or we have already used four of those types in this project (or in the case of Fire / Dragon, is too fan boyish).
This leaves Grass, Water, Poison, Normal, Psychic, Electric as possible secondary types...all of which look potentially cool (besides Electric lol).
I dunno, I'm not really a fan of Fire / Electric; Electric only covers Fire's Water weakness, and Fire doesn't help Electric too much besides adding even more of a weakness to Ground.
Fire / Grass on the other hand seems really cool. Grass covers Fire's weaknesses perfectly in the offensively and only Rock is not made neutral defensively. Fire also helps Grass out offensively and defensively.
However, what "real-life representation" could a potential Grass / Fire have? I don't know of many Flaming Bushes.
Fire / Poison is done easily with some sort of Volcanic creature implementation, like an evolution for Torkoal or something to that extent.
Fire / Electric I guess is already done for us since Manectric could use an evolution, is an Electric and already learns Fire-type moves.
Fire / Normal could be that lion or Prairie dog that people are referring to, since a lot of animals in GF's game seem to be normal (Zangoose / Dodrio / Tauros / Miltank)
Fire / Psychic I'm not sure of either, but it definitely seems to have "cool" potential.
Fire / Water is another weird one like Fire / Grass, but I really have no idea here.
For the next poll, I would definitely support Grass, Normal, Water, Psychic, in that order, for the secondary typing. If I had to only choose two, it would be Grass then Normal.
