I'm an owner of Age of Empires II and I love it. It is easily the most played strategy game in my collection and I own other popular strategy games such as Age of Empires III, Rise of Nations, and Age of Mythology. Age of Empires II keeps the game simple but challenging. The units attack and armor are very easy to understand (unlike newer RTS games where everything has attack bonuses vs everything else so you never know how much attack the unit really has unless you have a calculator with you). The game varies in difficulty from easiest to hardest and I have yet to master the hardest level against multiple players (I have owned and played the game for many years). If you want to play multiplayer online there is never a lack of servers ready for you to play. The graphics are mediocre simply because this is an old game compared to pretty much every other popular games these days. Even though it is an old game IT RUNS GREAT ON INTEL MACS, I used to play Age of Empires II on my G5 Tower, but since then have moved on to play it on my intel iMac, my MacbookPro, and my friend's Macbook.

Conclusion:
Worth Every Penny many times over, I have not played any other game longer then I have played this game. It is simply brilliant, from variety of units, to economy, to maps, to multiplayer and campaigns.
