With a wallet-draining mess of sequels coming out between now and the end of the year, you could say that 2009 is set to be yet another “year of the sequel.”  Now, we know that all of these top-tier games are probably going to be great—and we’d love to have them all.  But since many of our wallets are looking a bit thin these days, buying them all is going to be a problem (unless that plan to win the lottery finally works out).  So, if you could afford to buy only ONE of these games, which one would it be?

Halo 3: ODST

Forza Motorsport 3

Call of Duty: Modern Warfare 2

Left 4 Dead 2

Assassin’s Creed 2
