which came first-lost cost/epsiode 1

Lost Coast is just a 10-15 minute long tech demo showing off HDR lighting. It has nothing to do with the story line.ProudLarry

Lost Coast is just a tech demo. It has nothing to do with either HL2 or EP1.

ok and does episode 1 take right off from hl2simpsons1fan

Yes, thats correct.

Halflife 2
Episode 1
and later Episode 2

Thats the order, and lost coast does not fit in there at all. Like someone said, just a tech demo (but a very fun and pretty one!).

But it did become available for general consumption after Half-Life 2 and before Half Life 2: Episode One

And hey, it's worth a visit every now and then.
