The Vita is getting ps+ somewhen this month and if its anything like the ps3 one we'll be getting tons of games.
Could these free games make you buy a vita and if yes how many and wich games would it take.
some games that might make it to the service:
-Mod nation racers
or some thirdparty games though that's unlikely at the moment...
i think unit 13 or whipeout are a possibilyty (thats if they want to make a good impression if not it's going to be little deviants or reality fighters)
