Just to clarify things here... it looks to me like HTC is sending this to folks who tried a trial account but DID NOT subscribe after trying the 2 week trial.
They seem to be doing two things here.
****(This is just my Wild Assed Guess)****
1st, trying to retain some folks who try the game but don't end up subscribing. 2nd, trying to find out what the key reason is that these folks don't subscribe after the trial period. This is very valuable information to HTC.
There is a possible positive here for the HTC community in general. I'm sure if HTC finds out that the price is a big problem as opposed to other problems, the regular price could very well drop. If they can find out what the major reasons are that folks don't subscribe and fix those, there will be more folks in AH, and the price may drop. Additionally, if all goes well, HTC may end up with more income that will help them to develop the game.
This is just good business. This is all good IMHO.
As a community, the best thing we can do to get a lower price in the future is to get more folks into this game. Tell your friends, tell everyone about Aces High. Do what you can to help new folks into the game. Remember, every time you say "RTFM" when somebody asks a question you are keeping the price higher and/or HTC's resources lower. We trainers will try to do our best, but we need the help of the entire community to make AH a place folks will want to stay.
Cheers, and here's hoping HTC gets lots of new customers and lots of great feedback from this special offer.
