idk if anyone here truly LOVED Half Life and its successors, but the first time i played HL2 i was floored. i went back and played HL on Steam and it was grand. recently, ive been reading up on Black Mesa, a project that is going to rebuild Half Life from the ground up with updated graphics on the Source engine. they have a trailer, older than time, that shows off the polished look of the new game and it's possibilities.
