Final fantasy XIII should've remained exclusive

[forevercloud3000]

And have people forgotten that Mario Kart still sold 9.8million on the GC/N64 regardless of it being on ONE system and the LEAST SELLING one to boot? I use GC and N64 as examples of this instead of the PS1 and PS2's games that sold a lot because Nintendo was in the losing place. It just shows that games that are exclusive can still sell bucket loads regardless of how many more consoles the competition has over the other. :/
