i still don't understand where this urge for an application comes from.
BGA is built as a responsive site and works just fine when used in a mobile browser (which is the way I play it most of the time anyway)
true, there are some games that could use some polishing when in mobile view (i.e. Incan Gold when played with more players and i'm sure there are others) but overall it's perfectly acceptable
I also use BGA mostly on my phone, and there are several games that are really hard or even impossible to play on mobile (at least on mine).
Seasons is only doable if I switch to desktop view while assigning the cards to the three years (during setup), and then switch back to mobile view. Even then, sometimes the month-end result window will line up in such a way that I can't close it, which delays the game until I painstakingly maneuver it to where I can press that little x.
As you mentioned,
Incan Gold is frustrating/impossible to play because half the players' tents/gems are off-screen.
In
Jaipur it can be hard to select the correct number of camels/goods.
Backgammon is playable, but mis-clicks are a common occurrence when playing on a phone, because the stones are tiny.
Innovation is entirely impossible to play, because the cards don't display properly.
In
all BGA games, the game progression percentage doesn't show on mobile, which is an inconvenience in some games.
It's not a huge issue because there are plenty of games that work fine on a phone, but I can understand why people want an app.
