Did you even play Fire Emblem? The DLC was anything but BS. It was fantastic, and the game was utterly complete without it. They weren't selling the game piecewise, like some companies do, they were adding more great content to an already full content game. Full content game is here defined as having just as much content as an entry without DLC, which Fire Emblem and Mario Golf both fit the description of.
Of course I didnt play Fire Emblem. As much as I want to I have yet to find it for a price Im comfortable paying for it. Maybe I can find it used somewhere as it dosent seem to be in any decent sales ever =(
As for Mario Golf, well Im not buying that because I havent seen an RPG mode. I dont like the clothes mechanic for stats that they have brought in. I even brought Mario Tennis on 3DS VC to play the RPG mode instead of the 3DS game.
