Tim, one of the developers of Now Boarding game, showed quite interesting phenomena. Tim mentions that they created a web version of their game which you can play online (you’ll need to install Adobe AIR – which is fast & sweet to do – when you first launch the game). I’m going to ask a permission to share accurate numbers, but nevertheless it seems pretty decent tactic and has worked for them.
Take a look at the game and see how well they’ve done it.
By the way: the team is now having a special discount for limited time (don’t know how long), so if you want to get a discounted version, check out the purchase page.
