i know what you mean. i think the maps on Battlefield have a lot more to them. and the COD ones do feel quite flat. i mean even on wasteland its quite basic.
ive found that when you start favela people can just grenade anywhere and it somehow finds you! i too am on ps3 and the news maps i felt were not worth the money. but i will say that crash is a fun level for getting your kill streak up.
im a girl and it doesnt help when the guys on the other end rub it in my face. but always feels good when i chopper gunner their butts! but if any other girls are reading this do you find that all the players go for you if they know your a girl? i mean it doesnt happen all the time but when it does you get that lads just shouting abuse at you.
but red dead looks amazing, the i hear the multiplayer is a bit like World of warcraft as in you can travel through the online world in clans and stuff, i cant wait for it to come out!
