Great game... it was a blast
Some minor issues with game-
Towers are too weak,
can't build walls across trade routes ( I really like how they incorporated the native americans and the trade routes as well in this game. They're helpful but not over-bearingly influential. ),
I miss the castles of aoe2 (can't assign settlers to build fort; only outposts),
The campaign is not based on actual history
Gameplay: 9.5
They really seemed to even it out compared to previous aoe. No more building 100 scorpions. You need a little variety to be really successful. The settlers are stronger which makes rushing more difficult, and the minutemen creation can be called upon quickly if needed. However, it does encourage attacking play. Battles are back and forth and there are a wide range of strategies militarily and economically.
Sound: 9
I personally really like the soundtrack as well as the military screams, gunpowder, etc.
Graphics: 8
Decent graphics considering its now 2009 and It released in 2005. The graphics actually remind me more of Empire Earth than AOE.
Replay: 9
You might get bored of doing the campaign but this is one you can play online OVER and OVER again. Although there aren't a ton of games to join online, I rarely have experienced lag so the games are going great.
Overall, I love this game. it's a must have for RTS fans but will still be enjoyed for the casual gamer.
