I just got Singapore and am looking to give it a try as soon as I can get to a gameday. Depending on the game, I either dislike HTI or don't care (e.g., I won't play with it in T&E and couldn't care less in Keyflower).
Has anyone tried Singapore without the screens? Does it drive the AP up significantly? My gut is that Singapore is light enough that the HTI won't be a problem, but I was curious if people had tried it with the hidden information public.
