All in all, I actually like this better on the table then on the app.
While many people seem to like the app (i detest it!), i have yet to hear anyone say they prefer the app over the tabletop version.
I actually played Gates at the FLGS, so I know that that makes it even better.
That's the general opinion of GoA (not mine, though - i detest it, too ).
I want to play a bunch more times before I get the two Omens expansions.
OoI and OoD are both very similar to each other (in terms of setup and rules), and both provide a very different experience than the core game, more akin to (but distinctly different from) GoA.
