Is far cry 2 better than Halo 3

i play a lot of games far cry 2 is a big game like u can explore anywhere u want like oblivion and fallout 3. halo 3 has a good campagin but its all about the online there's aload of online achievements added last year for me its halo 3 its legendary, but its what you like, vast maps do what ever you want kinda game or loads of online play? remember though your always gonna get those people on halo 3 that play nothing but halo 3 and are impossible to play against
