I've played TNA and Pirates. I was in on TNA the day they opened the orders and am really happy with that decision. I am also trying to figure out how I can buy a Pirates next year, that game blew me away. As far as bang for the buck? At 8.5k for Pirates, that is a hefty buck but you can definitely see where your money is going. 6k for TNA feels right to me but you don't get all the fancy toys. You really should play them all though beforehand as they are COMPLETELY different games (at least TNA and Pirates play unlike anything else out there, my guess is GOTG will feel pretty similar to some other games Stern has made).
