Feel I ought to get on the L4D bandwagon but wondered which is the best to buy? Do i start with the first (as I would usually do) or, without any great narrative to worry about do I just dive straight into L4D2?
Get both. They are both as good as each other. I personally prefer L4D2 as it comes with a greater choice of armoury and I love melee weapons (sword, axe, guitar etc). Plus there are more special infected meaning if you play versus then you get a better choice playing as the opposing team.
