First of all, I’m sorry this is going to be a short post with no pictures or researched links, but you know how it goes around Christmas.
If you do need a little relaxation during those busy days, I recommend Sam&Max. If you’re feeling adventurous, get yourself the old one, from way back. If you’re less inclined to take a risk. Boot up Steam (you do have it, don’t you?) and order yourself the first season. It includes 6 games, each about 2 to 3 hours playtime. At least if you’re new to this adventure genre. Some people will probably finish it a lot sooner. But I’d suggest to take your time and enjoy the waky humor.
It’s Black Adder, but interactive.
