im looking for some good xbox 360 games.

i got an elite for Christmas along with Bioshock, Fallout 3, NFS shift, and PGR 2...

me and my sister really like Bioshock, the plot twists and gameplay are great.

i like fallout 3 for the open world and multitude of weapons.

i normally play games with a good storyline and action shooters. my sister normally plays classics and nintendo.

the racing games i like need to have a large variety of customization of cars, which is why i liked nfs shift, endless customization and amazing graphics.

i was thinking about getting Viva Pinata as a joke because me and my sister once sat in a gamestop for an hour playing their demo, and its only 7.99 used at gamestop.

halo 3 is what everyone says is a great shooter, but i don't want to get sucked into the endless halo franchise. so if im going to get a halo game its gotta be the best one out yet. (halo 3 got better ratings than halo 3 odst)

what games would you recommend for me?

also i need one good family party game, because all my moms seen is the gruesome killing in fallout 3 and bioshock. so shes thinking the xbox is going to posses me to go on a killing rampage across a college campus :P

so i need one good family game on the xbox. which is hard considering theres only probably 7 games that arent rated M on the xbox 360, not counting sports or racing games.
