I'll just go ahead and say this: If you put a game in front of me, tell me it's free, I will play it. Like, even if I only play an hour, you've got me at free. Free is the most amazing thing that anyone has ever invented and it will continue to reign supreme until the end of time. With that in mind, I'd like to pass on a note JunkyArd left everyone in our forums!
In case any of you are interested…you can download the beta here: http://www.ageofempiresonline.com/betaplay
Wow! Short and sweet! Thanks, JunkyArd!
