PS Vita / PS TV

I recently got a PS TV, and was pretty excited it also plays Vita games and other PSN games. I have a large amount of games from my PS3/PS4 that would transfer, but never tried a Vita. Without knowing much about the Vita, i assumed a Micro SD would work, but come to find out the Sony has their exclusive memory card, and they are ridiculously overpriced. This is old news to most all of you i'm sure though.

I know the vita hasn't sold well... and i have to think the memory card pricing doesn't help. It seems like if i did own a Vita, i would be steering away from buying games via PSN, due to the expensive memory cards. Do others agree this hurts the Vita appeal?

Secondly any physical game recommendations?

Thanks

I bought a Vita and i like it. I do recoment NOT buying sports or racing games for that. Sonic All Star Racing Transformed is the exception
