Timecards are an excellent way to avoid drawing aggro from spouses for your online gaming habits. The Age of Conan time cards come in a handy, DVD case which you can use to store any of your DVD collection and they come in a series of collectible designs. I always seem to get the same ones, so have managed 3 of the 6 designs thus far.
I find the cards themselves to have a sticky scratch tape at the back, so use a coin and be careful when scratching. It is possible to damage the imprint of the numbers and when that happens it becomes a guessing game.
In any event, it's a game time card. It is good for what it does. It is a bit on the expensive side, but is still reasonable compared to a monthly subscription and with all the changes made to Age of Conan over the last few months and in particular with 1.0.5 released now is a great time to come try the game again!
