Open Question: i need xbox 360 games what to choose what to choose?

i love first person shooter games like halo and gears, but my mom has to approve any m rated games, so far she has said yes to halo 3 but nothing else so you see my predicament. i need to know the t rated games that are fun and any m rated games not too violent and bloody. i’ve heard good things about burnout paradise i have all the burnouts for ps2. i’m gonna give you a list of the games i have seen and like and it would be nice if you could direct me towards some similar ones.
halo 3
burnout paradise
area 51 blacksite
ghost recon advanced warfighter 2
im not sure about the tiberium wars because its a third person view and im not sure i like that, if you could explain if it is good or bad that would be helpful, my birthday is feb 10 and i heard lots of new releases at the end of feb. any suggestions?i hear halo wars is coming out some time in april of 08 and im not sure if its 3rd person please if someone could clarify for me that would also be helpful.
