Vanilla versions of both of those. Better off just getting the GOTY versions in a B2G1 sale. Each GOTY version is gonna last you 100+ hours easily for a first run [assuming you don't just speed through it only doing main missions, which would be dumb with these games]. The DLC for these games truly expand the games significantly, especially for Fallout 3. I kinda feel sorry for anybody that only played the vanilla Fallout 3 (particularly if you missed Broken Steel).
