dang you have some weird prejudice against DLC. Would you buy a prequel game? Why should a DLC be any different if its priced appropriately and has a good story to tell. I'm not super big on DLC but if a game I love releases some then hell yeah I'm getting it.On the financial side, I'd assume most of you would agree with me that DLC costs money. I'm a really cheap gamer and I just rarely buy stuff.
On the player side, I rarely play stuff. Not enough free time so I focus on new experiences that can help me out as a game dev.
On the design side, playing Left Behind and The Road to Gehenna now would probably be great. It's been a few years so they can really stand on their own as short games instead of expansions.
