Does anybody here ever buy the same game for more than one console, either right away or eventually? I'm just curious about people's motivations. I'm sitting here looking at a copy of NBA Street Vol. 2 for Xbox when I haven't even unlocked any of the old-school players in the GameCube version yet. I got it when it was cheap during the KB sale, and I will probably crack it eventually, but there's really no rush.
Anyway, do you do it to make your collection numbers larger? Is it convenience? Is it botched frame-rates between two different versions? Extra features? Reduced cost? Portability, in the case of the GBA/SNES conversions?
Of course, we should open this discussion up for all systems, not just next-gens. For example, what's the purpose of owning the same game on SNES and Genesis?
