What should I buy on PSN?

Since the begining of the ps3's life cycle I have been without a credit card. As a result of that I have missed out on dlc and playable games that required a purchase. Recently though, PSN cards were introduced into the country I live in. I just bought one and now have no idea what to do what to do with the power at my control.
 
Anyone have any  recommendations as to what I should get?
 

if you ever played marvel vs capcom 2 and enjoyed it, i would get that

Twisted Metal 2

I enjoyed Trash Panic. But I would 100% check out Everyday Shooter.

" Flower "

Battlefield 1943
Pixeljunk Shooter
Flower 
Trash Panic
Trine

I made up a list of PS3 games here. Just scroll down and you should see PSN games. Of all the PSN games I've got. I think Flower is the best.

Thanks for the responses, I might go give flower a shot.

Braid?
