I've just completed the Orange Box and I can't make my mind up. Portal and Episode 1 were a big hit with me but were really let down by Half Life 2. The whole game however had terrible gun mechanics and was extremely easy to get lost with repetitive enemies, surroundings and corridors. :?
I really liked Portal and its really unique humour and gameplay. Episode 1 seemed a lot faster paced than HL2 with plenty more action and alot more shooting.
Tom has lent me Super Mario 64 and Lost Planet, I'll probably use those two as an excuse to write a new blog soon. I'm contemplating buying Army of Two after seeing some more videos of it asnd having a look at the achievements.
Your thoughts welcome as always. (Cheeseeeey):P
