which game purchases this gen have offered you best value for money (full price only)

[TRios_Zen]

Gears 1 - 3: I've put countless hours into the MP of each of these making each worth every penny (and then-some).

Single Player wise Fallout 3, Oblivion and Skyrim. Over 100 hours in each. Hell I don't even know how I found that much time TBH.
