No encyclopedia is a good source- encyclopedias are not sources, they are references. Find the source. Wikipedia just happens to be less reliable than most, esoecially in areas like gaming. We just had that with the complete false claim in the wiki article that the graphics were to be comparable with the 360, which is nonsense. The term the devlopers used was that they wanted to make it 'competitive'. VERY different. Super Mario Galaxy was competitive, looks wise. No-one would call it comparable to the best 360/PS3 games- but that didn't matter.
I still worry this game is mostly hype. The interface options etc. are good but... it is just the underlying game seems so bland.
