Right I only found out a few months back that you could now get Steam on your Mac and since then have played through Half Life 2 and Portal, absolutely loving them both.

So what's next? Is it worth downloading either or both of the Half Life 1 episodes I missed after the original came out (Blue shift / Opposing Forces) or should I give them a miss and just jump straight into the 2 episodes to the sequel? I'm guessing they're pretty decent?

Also, I see that Portal 2 is £3 cheaper if you order this week AND you get Portal 1 for free or to pass on to a friend who is also on Steam if you already have it.

I've just ordered it. Just hope it plays ok on my aging Mac. It's going to rock, isn't it?
