Age of Empires 3
i loved AoE2. i hated AoE3. the reason? the time period. the game flouts having huge battles and the like with cannons and muskets and such. but, when you have cannons that can reach a third of the map away, infantry that know no tactics, and a 200 population limit, i found it hard to like. there is no real tactics in the game. if you have a lot of cannons and some anti cavalry units, you can defeat everyone. and i mean, everyone.
so, it sits in my shelf.

Ghost Recon Advanced warfighter
paid $60 to get the collectors edition. dont know why, mayve because i got a $70 gamestop gift card and i didnt know what else to buy. well, i got it then found out it couldnt run on my computer. put it away until last year. played the frst two missions, got stuck, uninstalled when my hard dive got wiped, played a bit of it a few months ago, uninstalled it to make room for ETW.
it was a tactical, but kinda lame, game. the tactical options were limited, and your stupid teammates always got themselves killed. i hte the non rebounding health meter becase there are some places where you get killed very quickly, or your health gets really low and you end up restarting because if you dont have full health for the enxt mission you would die in the next stage. as i sad before, tactical options were limited, and the multiplayer is the definition of lame.
