Which series is better: Zelda, Ressistace fall of man, or halo?

[Riot Of The Blood]

Fine.
Sales:
Zelda series>Halo series
Sonic series>Halo Series

blah, blah, blah.... I can list plenty stuff that has marked it's place in gaming history and has outsold the Halo series.

Sales have nothing to do with Quality. Just look at the Wii. It's a horrible console and it outsells the ones that have good games on them.
