the more i think about it, the more i can't rank them. they are all so good in their own way. i own them all btw.
GZ is funny. Maiden rocks. JP is an adventure. AIQ is a deep battle. they all shoot well. most importantly, for me, is that they are all deep enough code wise that i will never become bored. i will likely never see the end of them either! kind of like questing for Valinor. the important thing is that i can get deep enough in all these games that I believe i will make it to the end.... but i never quite do.... Go Keith Go. I will buy all your games. they are fun to shoot and challenge my mind.
