L4D2 mod that has put all the L4D1 campaigns in L4D2, jeez can't modders leave games alone??? if u want to play L4D1 just close L4D2 and load up L4D1 in steam, it's not hard. the improved graphics maybe cool but valve could just do that and release it as a patch, and graphics don't count anyway - gameplay does. I just don't understand why people can't leave games alone
