This is free for the Vita and I'm not going to lie I just download all the stuff they offer even if I had no intention of playing it. I was on the throne today and said fuck it. I was expecting a really bad racing game that was clunky and not "fun". I have only done 4 races and I cannot say for 100% yet but I think I might like this game way more than Mario Kart 7 and I really like Mario Kart... The levels are great, I didn't play Diddy Kong Racing so I don't know if you swapped between Car and planes mid level like you do in Sonic (ooo and a boat) but it is bad ass. The music is good. Because of all those things I really want to play it on my big screen and with speakers. I might pick it up for console so I can also play with the lady.
It's really a fantastic game. Fun, tons of content, very well made. My buddy played the original and said it was surprisingly good, but I figured he was full of crap. For some reason I picked this one up and put around 30 hours in.
I didn't install it on my Vita yet because I know I'll just start again, and I have a bunch of games to play before things start coming out again, dammit.
