Seconded. It was wonderfully done with a lot of effort, time and attention put on it. Thanks Two Sigma for doing this! Would definitely play if this there going to be a Halite 4 or something else.
I have played in Ants before but somehow did not hear about Halite 1 and joined the Halite 2 at half way stage, remaining a huge fan ever since.
Some suggestions too for the future , if I may.
-
A more lightweight web based game player, lightweight means it can be played on most browsers (including most phones) and can be played quickly. Ability to see a game with least amount of hassle is doing a lot for the popularization of the game I think.
-
Some form of active battles (similar to Ants, planet wars or Halite 2) make viewing of a game much more interesting to all levels of people, again would help to attract more players and viewers.
-
If a bot can write to a simple text file, suddenly there would be more possibilities open for machine learning and adaptive algorithms to flourish since bots could try to learn from previous games. Say, data.txt with 100KB of max size.
-
leaderboard with pagination size of 100 players per page. (like was in Ants) Think this simple change will improve competitive level and enthusiasm and intensity for many, humans like to appear on front pages 
-
Now that you have a flourishing and committed community, may be can initiate some kind of a collaborative project in between times of competitions. It could be some AI related research or charity based open source development project. I would like to contribute if there is some initiative. Think there would be many more if the project sounds interesting and useful towards some worthwhile objective.
Thanks again!
