I'm also taking out humans, because if the timeline is TLF -> This Game -> AI War, as makes sense, then humans would not exist yet.
So no greeks or nords?
What about the Creator(s)? ;-) You do like asymmetry in your game design. . .
if you use a
tidalis --> shattered haven --> skyward collapse --> valley 1 & 2 --> bionic dues --> tlf --> air war --> spectral empire timeline
then, actually i believe we could have any and all of the races, including human (several versions of humans from the different games), including the greeks and the nords and the demi-gods and the creator, and the grays and humans (call them SH humans) among the AIWar Humans, and the Valley Humans. You could even, if you wanted, keep the same animations and character sprites from all the older games and put them into the new game ( to save money and because the fans would love it anyway).
just put check off boxes in the setup area to add them to a game. From 2 to 54? (i can't remember how many characters there are across all the games, probably a lot.)
of course if you wanted you could create new character sprites, in a new style, where all the sprites sort of have a uniform or similar look to them, if that is what you prefer instead. but if you do re-use the older sprites, then its almost like a nostalgic send back, you know?
for 'serious' games the old sprites don't have to be used where everything is like super intense (use the new uniform look style for the new game for those games instead) ...
but then if you wanted you could add the tidalis and grays and the SH humans (who are kind of cartoony, but who cares?) for a free for all, pull out all the stops! i am doing all of this now! game of hectic and hardcore and lore-laden Arcen 4x Mayhem!!!

p.s. of course if you used all 54 races in a super-maxed out total blow my mind game, then you would have to have randomly generated maps to accommodate all of the races.
but hey, i'm not complaining, i'm just trying to convince everyone this is the way to go!
