finished HL2.
The ending did not suck at all! Although it did come unexpected. Btw, gordon does not die because time gets frozen. And actually i think its a lead to HL3. Remember the teleporting with Alyx? The scientist said you where away for a WEEK. Though it was only a few secs for you and alyx.
The g-man really rocks, though its very hard to spot him. I have seen him 2 times appearing in the game. I bet he is mroe often visible, though you are busy with so many other things
Also, noticed the ending is the same as the begin? (the stars, and such). And, as the g-man said, it also looked to him you did your job within a few seconds too.
