So... i got GTA4 and MGS4

i wanna get Bad Company

MGS4 has a trade in value of $25
GTA4 has a trade in value of $20

i think i wanna get rid of GTA4 cuz i dont have the desire to play it again and the Multiplayer is not as fulfilling. i wanted it cuz my brother in Japan has it and we can merk each other. but... i REALLY want Bad Company.

is this a smart move?

also if anyone has COD4 for a good price lemme know
