Q*Bert IS isometric. Just going down a lot, so it's lots of isocubes and looks hexagonal.
And Settlers has strange shifted squares as tiles i think like this kinda \ \
History Line has hextiles, as has Battle Isle.

I read somewhere's that even though it's made of isometric cubes, the game was coded with hexagonal tiles. I could be wrong though.
