Hah, I do the same in AoE 2 as well, though I put the AI to standard and like to give them grief, like build towers around their base early in the game, or use an army of monks to convert every unit they send towards my base, and build up my own army of converted units; or lure them into my base by deliberately leaving a gap in my walls, except the path to my tc is lined with towers along the way - sometimes I even make a maze of walls and towers and it's fun picking them off one by one as they make their way towards my tc.

But lately though, I've been doing all of that in 0 A.D., an opensource RTS like AoE. One of the cool things about 0 A.D. is the soundtrack, it's really, really done well, especially considering it's a free game; and I also like the customisable AI - in addition to difficulty, you can set their behavior to defensive/aggressive/balanced etc, and you can have a ceasefire period where the enemy doesn't attack you at all for x minutes after the game starts, which gives you enough time to build up your base.
