It's a very simple design that is excellent both aesthetically and in gameplay. Unlike 90% of the risk maps out there, everything isn't so intertwined. It's harder to position yourself for kills and it's harder to tag team the big players (since they can heavily fortify one slot in a tunnel instead of having to spread their troops out). The unlimited reinforcements only increase these effects. But to me, there are neither advantages or disadvantages; it's only perks that make this map unique. These settings more than anything reward smart play. No longer will the mediocre participant who is lucky enough to take her turn after a noob flails about the board be able to combo several kills for the victory. Again, this is both the map's greatest strength and greatest flaw. Cheers to the designer(s).
I liked it back on Warfish, and I still like it now. if you have the full 16 people on it it gets way hectic, but that can be fun too (assuming you don't get smashed by the time it's your first turn).
