Guys,
Which is better, “cartoon-y” or realistic?
I would love to here your opinion,
Monkey 
I think cartoony because lots of popular games use it, like every single one of the hotel games. What type of genre are you looking for with your game?
Not sure, I love building either.
I love realistic building, it can be complex though. Sometimes I build between low-poly and realistic builds.
We all love a bit of Low-Poly in our games. As I am a self-taught Low-Poly developer, I would have to say low poly is definitely more better in games.
It gives of this wonderful vibrant colour where with realistic, it does tend to lag users and it lacks the quality.
