How can you not want to play Portal? It looks very very good. Oh well, each to their own.
It's probably simply that ep:2 is only a few hours long that it's not being released on it's own.
Valve are set to review their episodic release policy soon, so we may see some changes in available packs. i.e. A half life pack, that gives you a discount based on episodes you already own would be a good idea. I.e. HL2 pack = $40, -$20 HL2, -$10 Episode 1 = $10 to pay for episode 2
