5 fantastic games in one!
the time ive spent playing team fortress 2 alone makes the price tag worthy. TF2 is great even for a beginner to pick up. since i lose patience with the elitism of black ops i found it ideal to get back into first person shooters.
Portal is great fun and a good puzzle game, so much so that i will soon be getting Portal 2. the ending credits were also worthy of a few giggles.
as for half-life 2, episode 1 and 2 theres probably a good 20 hours of gameplay plus a lot more if you want to unlock all achievements. the only thing i wish this game had was a co-op mode.
