What does "Classic" or P1999 really even mean?

[Lazortag]

Using p99 as a pvp server basically means that the PvE aspects of the game will be extremely well coded (leagues better than any other emu server), so the devs can spend much more of their time fixing pvp issues instead and policing things like cheating. Which also means they'll be less likely to get burnt out from the overwhelming amount of work.
