Played Anno 1800 a couple years ago, good game and pretty. But the original Anno 1602 still wins in the looks and style department. As most 2.5D isometric games do..
Hmm I feel this might just be nostalgia at play. I've not played any Anno games, but comparing the two side-by-side and 1800 looks leaps & bounds better to me. 1602 looks like it was drawn in MS Paint.
My point was 1602 holds up visually in a sense of doing it’s job assisting the game mechanics, something most modern games often fail and over complicate. Also.. nostalgia.
