Traveller's presentation and design vaulted it years ahead of the competition in 1977. Those three little books are RPG icons, with their minimalist black-and-red covers. The rules hit a near-perfect mix of elegance and comprehensiveness that few games before or since have matched.
In the trailer, the game resembles an upgraded, multiplayer version of Space Trader, which I played obsessively on my Sony Palm device six years ago. Of course, Space Trader was an obvious homage to Traveller, so the similarities are no surprise. I don't use iOS, being an android myself, but I plan to insist that all my Apple-using friends install the beta and then borrow their toys to take this for a test jump.
