what should I buy halo 3 or odst

i have never played halo before and i love multiplayer games my friend already pre ordered halo odst but would i be saving my money on halo 3 what the better buy

I think Halo 3: ODST is the better choice since you get Halo 3 multiplayer with all the maps. Then wait for Halo 3 price to drop to play the single player or even rent it.

halo3 sucks multiplayer unless you drop alot more money for the maps. without them your stuck to one game basically. i will forever hate bungie for that. no odst for me either.kit352
