Okay, I've done my research. According to 1up,
Soulcalibur IV is better than MGS4
Wii Music is as good as MGS4
Wii Music is better than Resistance 2.
Fanboys.
I am aware that they are different reviewers, but still. Soulcalibur 4 is NOT an A, Wii Music is NOT an A-, MGS4 being an A- is debatable, and R2 is NOT a B+!
EDIT: Let me put this into perspective.
Soulcalibur IV. 1UP: A. IGN: 8.7. Metacritic 85
Wii Music. 1UP: A-. IGN: 5. Metacritic 61.
Resistance 2. 1UP B+. IGN 9.5. Metacritic 91.
MGS4. 1UP A-. IGN 10
Notice that with both of the exclusives, the IGN score is higher, the multiplat, 1UP is slightly higher, and the Wii exclusive, (according to metacritic's letter-number scale) is 41% higher on 1UP than on IGN.
Pretty much the same thing with metacritic.
