PS is
- MMORPG, with a lot of other (usually) cool people
- evolving all the time (like Linux

).
HL2 is
- FPS, single player => really a great game by the look of it, short life
- MP (DM, CTF, whatever) => good to wash away the stress, especially after one of those days at work. Don\'t play at this too long though, it\'s not healthy
- (I know, the mods ... but it\'s about MP - yeah evolving too

)
So to me, those 2 just don\'t compare. It\'s like a long summer and an occasional rain (ouch this is sooo bad, please delete that ! :rolleyes: ).
(don\'t take me wrong, as soon as HL2 is there, I will rush to the store ! And one week later, it will be a good game to remember about)
And the others xyRPGs, well, once you have settled at one place, it takes a lot to make you move - one day has so many hours, not more. Unless it\'s really worth it, but I can\'t see a good reason among the other xyRPGs out there.
Errrr, what was the question already ? Ah yes : with no particular order of preference,
- RP, guilds, ...
- people
- under perpetual developpment and improvement by a very good and dedicated team
- 3D 1st/3rd world, very nice graphics
- rooftops (did I say that ? really ? must be a glitch)
- the quests. Why, it\'s a refreshing experience
- did I say free ? Oh I would be ready to pay a fee for this (a few rubies every month or so)
and probably a ton of other reasons. But I must go ...
