MiBR vs fnatic at ESWC was good! but my favourite match ever has to be mouz vs MYM.pl (or whatever they were called back then) when they played on dust2 and I could be wrong but Tixo won a 1v5 eco, Kapio stabbed TaZ to win the game and cyx was just INSANE all round! (probably didnt all happen in the same match though...I think it did)
Few, but I like the most:
PGS vs NIP @ WCG 2006 Grand Final
NIP vs SK @ CPL Winter 2005
FX vs MTW @ Xperia Play 2011
FX vs SK @ WCG 2011
And one match Fnatic vs MTW,but I don't know which event it was. That was a match on De_dust2 when f0rest did some big plays defending B.
Na`Vi vs mTw WCG 2k10
3D vs fnatic eswc 2006 @train
SK vs 3D, CPL Winter 2005 @Nuke, Fiskerjump =D EPIC
And if anyone can help me remember, a match NiP vs 3D on Train, where HeatoN with ak47 was destroying in T side, what tournament was?
