How do you know you're horrible at if it you didn't buy it? Just use the buttons not the touch screen.
I played the Steam version. I used Roger.. and brought his great name much shame...

EDIT: top of page recommendations
Persona 4 Golden $30
Virtua Tennis 4 $15
Sonic All-Stars Racing Transformed $20
all currently on sale and good if you got the money for it

for every $50 spent on the PSN store, you get $10 back in April.. (offer ends March 31, 2013)
EDIT 2:
do I really want a Tennis game (that I am horrible at) for $15 when I just bought it at $3 on Steam? :/
