Glad for all the feedback, I still think we should have to venture out and get them ourselves as it gives us an extra challange, you kill the guy and want to mock him for it, why not have to go through a bit more to do it?
Maybe I was wrong about making them customizable (SP?) as the SEALs are obviously all the same in relation to details.
Also someone said something about only carrying a certain number each time, why? If you play a regular game yuo die only once anyway and in a respawn you die then come back alive (the whole point to respawn) so surely while he is pleeing with the higher authorities to let him go back to earth and fight he has the time to pick up another dog tag or 2 while hes there.
Creating a limit to the number of tags you can store is a good idea though, maybe upping the limit to 20 or so would be better. I cant see the tag taking much more than 1mb tops. Even if it was to implemented in a game it wouldnt be until the release of the PS3 anyway so we can store our own tags on our own HDD.
