The Witcher.
Mass Effect.
Dragon Age.
Transformers.
He-Man.
Jeez would I play the crapola out this game if it was done even remotely well. As long as it stayed true to the G1/G2 era. None of this modern day movie stuff.
This was my main infatuation as a young boy, and still holds a special place in my heart.
Zelda
Path of Exile
Wither maybe…but that wowuld require lore
Mass effect…yeah…no…storywise would be a nightmare unless you put it in the Andromeda arc
He-Man…maybe…but 80s stuff won’t vibe
Transformers: Maybe if they don’t go with the bayformers crud
Fable universe. Plenty of well expanded-upon lore and landmasses that’d be brilliant in the form of a huge, seamless map. Nice toony artstyle that lends itself to good art direction, reasonable system requirements, and lots of units on screen, too.
