Essential:
 * Multiplayer with at least 2 players.
 * One civilization (Hellenes) in a balanced state.
 * 2-3 maps.
 * Enough art to support the maps and civ we choose.
 * Non-working features hidden from user interface, non-existent units disabled, etc.
 * Sufficient testing to ensure stability and performance on a wide base of systems.

Inessential, but would be nice:
 * Easy to use game settings program (beats editing user.cfg).
 * Rudimentary matchmaking service supporting NAT punchthrough.
 * Hotloading in Atlas.
 * Rmgen integrated into game engine.
 * Review and update of the profiling and crash reporting tools.
 * Sound.
 * Some sort of single player sandbox, like maybe a simple "fixed force" scenario where you fight against a static enemy.
 * (Better/automated) Compression of the data files before downloading.
