Ultimately, they are both games: nothing we do in either title will matter
I am curious, how does EVE the game 'change' where as PS2 will not? It is being developed by a company, it is patched and expanded like a regular game, etc. I would say the thing that differentiates the two most would be the timeframe of play.
In PS, if I make the wrong choice between jumping in an aircraft to help clear a courtyard to relieve pressure on the players inside, or jumping in MAX armour to help reinforce the defense at the back door, we'll lose the base. This can happen in minutes.
In EVE, if I make the wrong decision in either jumping in a logistics ship to support the fleet, or a combat ship for more focused DPS, we could lose the battle, then a POS, then a system. This could take hours, days, or even weeks. POS's lost will be rebuilt, and stations remain static and are flipped.
But I digress..
Dust 514. Jumping on the, "I was excited for it till it was announced PS3 exclusive", wagon. So sad.
