eve has been out for almost 10 years and yet so few other companies have made an MMO with the design basis of eves PVP. and it amazes me because it is still the most complex, in depth and involving gameplay experience of any MMO and noone has made a success of using those features in a different environment (fantasy etc)
some have tried and failed but that is more down to the fact that they were so awful in every other aspect rather than using eve template. eve has had every player in the same server shooting each other, and yes at times the lag is awful, but i remember pvping when the game first came out and i was using 56k dial up and it was still playable in smaller engagements (although the number of players was signifgantly less than it is now)
time will tel how PS2 does but i hope it does really well and not cater to the fucking carebears! shoot them in the face and listen to them scream
