Kinda what happened to me a couple years back dude.
The demo's for the BF games always seemed a bit dull so I avoided the games & stuck to grinding prestige in CoD. Then I wanted to beat a rented BFBC1 for gamerscore & tried out the MP for a laugh, I thought it was amazing (especially compared to that 'same ol' CoD) & never went back!
Choppers! Quads! Real
Sniping! Games that can last 30+ mins with no damn lobbies!?!?! OH YEAH!
