I don't know if anyone here used to play this but the original Planetside contains all my favourite online gaming experiences. It was a land based, future MMOFPS game. At it's height it ran massive online battles between hundreds (really) of people. I remember with awe hundreds of people attacking bridges and towers.
Imagine Battlefield on a massive scale. Instead of 32 or 64 players imagine 500 players all flying aircraft, manning turrets and driving ground vehicles.
Yes, Sony made bad decisions that (for me) changed the game for the worse and eventually made me give it up however at it's height it was a gaming experience i will never forget.
This guy gives a good account of how it felt. I just hope PS2 can live up to what i remember of PS1 and I don't just remember the rosy moments and not the bad.
I can't remember being this excited by a sequel to anything..
