GTA5, but love them all. Battlefield 3 - loved the online matches; 'Conquest' was where it was at--rolling around in a tank with total strangers, playing in perfect harmony. C.O.D. 4 - the GOAT of CoD's RDR2 - What a story and everything else. Of them all, I probably spent the most time playing BF3, but it's hard to say which one I enjoyed the most.
