Looks like a pretty decent multiplayer map. Why on earth would you restrict this to 1v1? As a 1v1 map it's terrible. Nobody enjoys 1v1 games on large maps. As a general rule, people enjoy games where there are about 7 to 15 terts per player. Less than that and there's not enough options. More than that and it becomes more work than play, keeping your empire organised.
I'm not trying to be negative here. I actually like the look and feel of this map. However, I wouldn't want to play with less than 6 players.
