I'm looking to spend $6.99 on a App and I saw that NFA and Tiger Woods are on sale but, is it worth the $6.99 to spend on either on of those apps? I also need this info: How much gameplay time does each game have and if there is any replay value also please. If there are any others please let me know. I'm leaning towards Tiger Woods but NFS looks really good, but I have Real Racing though. Thanks!
