Hmm....not a bad price, I wonder if it's worth it though. I bought the Tribes: Ascend pack for around $10 and never really ended up utilizing it much because the player base died out.
So far the gameplay isn't really impressing me beyond what I played in the original beta...a lot of running around in a circle and eventually just getting reamed by the monster.
I'm not sure we can really judge the longevity at this point because there are tons of new players which leads to the boring 20 minute monster chase. I think once we hit level 20 and unlock the ranked playlist that it will be a whole new game.
I was paired up with 3 other good hunters and a good monster last night and had 3 close matches filled with non-stop action.
