I was looking over the Alawar site today and noticed that they have changed every game page that I could find. I could NOT find a single page (from the oldest games to the newest games) that have a "buy now" button. All of them only have a "download trial" button.
However, that does NOT mean the games are not for sale. The description on purchasing on the right side has changed in all cases. It used to refer to the buy now button (that was gone) and so was confusing.
Here is an example of the "new" text -- taken from Treasures of Montezuma 3
To activate the full version of The Treasures Of Montezuma 3, copy and paste the registration key into the appropriate window. To obtain a registration key, run The Treasures Of Montezuma 3 and then select your preferred method of payment.
Note that you CAN buy the game - you just have to download and and at least start the trial version on your PC first and then purchase the game.
I don't know what it does with that stupid wrapper but the games are available for purchase there.
I'm glad to note that because I do surveys for Opinion Outpost. They have a new program that for 30 points (equivalent of $3), you can get 1 game! I need to earn my points to get Treasures of Montezuma 3. I know it's reviewed to be inferior to the other 2 in the series, but I still want it!
