I have heard a lot about both of them and am curious which you all think is better. I did search and looked through about 5 pages and did not see one like this although I bet there is one but since one of the games just got a large update I think it would be value to repoll. I will probably end up buying both but I want to get just one before 3.0 comes out as I have only one space left haha. So vote away.
Blue attack is a high scores game, blue defense has customizable options and deeper gameplay. Your call.
They're both great games, they're just different. Personally I love Blue Attack but the use of accelerometer exclusively, makes this a hard title to go back to now that I'm spoiled with virtual analog sticks. It is worth the two dollars to have both on your ipod however.
Blue Attack was just shabby. It looked nice, played terribly. I can't stand it. But Blue Defense is a freakin' classic. I love it. So much addicting fun.
