yeah i heard no prestige on the pc - but i dunno if ps3 has it too...?
i didn't think i would go for it, but it offers up a fun challenge to unlock everything again. it also makes u work with every gun and many diff game types to help u get more xp.. that is, if ur good enough - otherwise, u will just waste time trying to get kills with weapons u may not like. its a challenge to figure out the perfect blanace of "how many kills/points can i get with weapon X" vs "how many points will i end up getting for unlocking weapon Y challenges"
i just started 2nd prestige & love the change up even again
