Well this is the final checklist. Funnily enough it didn't come down to just Live 10 vs. 2k10, but Live 10 & FNR4 vs 2K10. Hard to beat. Anyway i'll be picking up Live later today, but this is my pretty final feature checklist.
Head to Head
*Features I think go head to head, winner as of now is in bold*
NBA Live 10 / NBA 2K10
Synergy DNA / 82Games Tendencies & Living Rosters
Individual Player Momentums & Quickstrike / Revised Isomotion
