What's the single best game you played in 2010 (so far)

[d21lewis]

2010 gave us Red Dead Redemption, Mario Galaxy 2, Other M (I loved it), Bayonetta, Heavy Rain, Valkyria Chronicles 2, Halo Reach, and several other great games.  To me, the two that stand above the rest are

Super Street Fighter 4 (runner up) and Mass Effect 2 (takes the crown).
