Simple Answer : people would abuse it.
Explanation.. of his explanation (his post before the one you replied to), if I wanted, I could make a trial account, fly for a month, make a new one and do it again. Unless HTC has some way of preventing that, then it would be abused. Someone returning like ManAWar or Midway
, it's about the only con in-game that I can think of. The only other con would be finances, HTC is sticking their neck out further, offering a longer trial, but no guarentee that the player will stay just because they extended the trial.. however, there isn't a guarentee they are going to subscribe if it's just at 2 weeks either.
If this were true 2 weekers would abuse it as well.
Giving a new player a couple extra weeks doesn't cost HTC any money as all the systems are there and they are paying for it all ready. If they had to add more servers to accommodate longer free time then I could see your "cost" issue, but they don't need to as it has been said by HTC that the servers aren't at 10% capacity.
When Fighter Ace was closing I think HTC extended the free time to 30 days. So it can be done.
Personally I think they need two things. A training program That shows up first time you open the game. Nothing to long, but a short video explaining the training arena, how off line practice and missions DON'T count toward your free trail time and to encourage new players to get familiar with the game BEFORE logging in, along with a couple print outs.... dot commands, keyboard commands, and links for "More info" like the new videos Skuzzy is adding the trainers site ,BBS, and so on. Force feed the availability for HELP to these people.
Second, an extra couple weeks on the free ride. A way for them to fly in the training arena with out it counting toward their trial time would be good to. Keep the no damage, but at least this way they could get training without feeling like they are "wasting" their "free" time in training. They could get some time working on flying against people instead of drones, a bit more realistic taste of game play. Maybe a 30 free trail for the training area that is separate from the 30 day game trial.
They need to give these new players a chance to survive and learn long enough to get hooked.
