shit, you like what you like...
A few i can tell you have a VERY hi replay value are Tiger 2010, Skate 2 , and SF4 ... Im not big into the skating games but Skate is at least worth a rent, and it has tons of shit to do , and huge area/cities etc .. SF4 Is great if you like to master a game.. Tons of combos, new characters, And aton of online options, and some pretty unreal online competition..
Tiger... Well i like golf so this is bias ( based on that ) But replay value... is huge... Yea its the same 15 courses or so , but it always changes, wind, ( live weather by the weather channel ) , green speeds fairways etc Lots of missions, games, drills, etc But the thing that makes this game huge is online... There is just to much to say what you can do online with this one. Competitions, ( weekly , daily , play the pros tournaments ) battles, In game real time sports tickers, updates, EA gamernet challenges, posting your highlighted shots online for others to try to duplicate to earn points etc
