I hope you enjoy it, ag_1988. I had never played an RTS before until a group of gaming friends in another game pirated the original way back in early 2008 when the game came out. I read reviews and watched YouTube videos and decided to gamble and purchase it (because I'm not a pirate). I quickly fell in love and it's been my #1 game ever since. If you really get into it and learn the game well, you can also play it against human players in online multiplayer, which adds an entirely new dimension to the game's strategy and makes it much more interesting and fun IMHO.
Be sure to read this thread first if you ever play online since you might have to fix the Mesh Error:
