First there was COD 1, then 2, then 3, then 4. You get the idea. This one is the latest and greatest (for about 6 months) so make you get to prestige before then. By that time the next one will be out and you will pony up another $99. Unless of course you buy yours games through cdkeyprices. If that's the case...all power to you!
Always read your chosen stores product description before buying your Call Of Duty Ghosts CD Key. Check they are in stock, as well as any activation methods the cd key may require.
