I really don't know if your being sarcastic or not, lol. Either way, it's actually worth it for that, even if your only playing ported PS1 games..
No sarcasm. So far I've re-beaten only Soul Reaver, but Cool Boarders 2 plays great and with the way you can drop in and out of games, I can't imagine not having the system in my bag.
I like the PSP Grand Turismo just fine, but a true Vita version with fleshed out modes would be very much welcomed.
I haven't actually played a real Vita game since Sound Shapes. I think that's where all the complaints come from. It has to be, because there's certainly no lack of content on the PSN store. They could permanently drop some prices though.
