After that it's harder to define a correct order but probably:
ME1 +ME 2 - absolutely love the series.
DA O - great game, got addicted to it straight away and it's probably the game I've finished most times (not the one I spent most time on though, that honor belongs to OB of course :tes:)
FO3 + FONV - both are awesome, though I admit FO NV is a superior game. IMO they don't have the charm that TES has but none the less great games.
Ratchet & Clank (the entire series) - my favourite PS exclusive series ever.
The Legend of Zelda: Wind Waker - my favourite Nintendo game of all time. Just awesome.
RDR - all around amazing.
Canis Canem Edit/Bully - one of the best games ever released for the PS2 and one of the best games Rockstar has ever done.
Jak & Daxter (the original trilogy) - the 1st game of the series was my first PS2 game and although I already owned several games before it was the first game i ever felt I owned. Very good series.
The Witcher (especially the 2nd one) - one of best RPGs I ever played.
Among others
