A: While it won’t change the fundamental awesomeness of Aquarius, there turn out to be quite a few differences:

1) Card size is changed to the narrower Fluxx-sized cards, and deck size is increased to 100 cards.

2) Triples (cards with one half-panel, and 2 quarter-panels, including both horizontal and vertical halves.

3) Rotate Goals changed (back) to Shuffle Goals.

4) Rules to a new cooperative game, suitable for very young players: Maze Escape!

5) Number of Wild Cards increased from one to two, AND now usable as a Wild Action if so desired.

6) Better Quad randomization.

7) Vertical Aces
