Or, Why buy the same game twice?
Because it's fun...
I'm w pichu on this. Nobody complains when pes, madden, nhl or any other sports games feels exactly the same. Why are they complaining about this? Besides they added a lot more to the game. Sports games update the rosters & add a few changes, not nearly as many as animal crossing, yet they still get rated very high, why? Because they're FUN, and that's all that ever mattered.
