Rockstar is giving us an execllent reason to be thankful this thanksgiving! Yesterday they announced quadruple XP from the 24th to the 27th! So if you haven't hit level 50 legend 5 yet then be sure to jump on in between eating and shopping!

PS: (unrelated game note) If you're trying to get the "Story Teller" Achievement/trophy in Batman: Arkham City don't forget to talk to Calender Man on Thanksgiving!
