Yeah PS2 will have plenty of vets from PS1 to "steer it in the right direction" (yes, a subjective statement, but it's a subjective topic). And just think of it logically; when PS launched in May '03, there were no vets
somehow, people figured it out (and the squad/platoon/outfit system definitely facilitated that). Those who cooperated and communicated generally succeeded over those who did not, and people don't like losing so cooperative play styles were adopted (until the BFR took over and then the mossy became a flying mini-BFR)
