As a new player, I just wanted to say that I think Hi Tech has hit upon the best thing yet to improve game play, broaden the player base etc.
Offline practice, including missions and such is just what the new player needs.
Practice against opponents that fight back without out the intimidation factor of the main arenas
is going to appreciably help the new player gain skills and confidence for online play and will help the new player retain interest.
Making mission downloads available only to subscribers will encourage subscriptions and guard against those who might otherwise consider it a "free" stand alone game.
Bravo Hi Tech, Bravo.
