I often read in game magazine forums that people would love to buy DLCs - kinda like "shut up and take my money !!"
I always shake my head over that.
I guess since Expansions become more and more rare, and DLCs more and more frequent (like a set of scales with one side going up and the other going down), I assume that younger generations are just being "trained" into buying DLCs rather than expansions.
