I didn't mean to suggest that others were refering to the graphics when talking about the game being cartoonish, but rather, as you mentioned, the battles are easy and the tooltips, like the voice characters say stupid things, obvious things to guide you through the game. It actually looks a lot better than
WC3, and better in-game functions, but seems very limited in what you can do. This is because more effort was put into those show-off functions than actually being an undefined world - as opposed to being a defined and limited world with limited user-interaction.
I've not tried it yet but it looks good, like worth playing.. So don't take my word for it.
